rather it's a product by o w i and i use a lot of their products in my classes because they're actually really nice products and they're easy to build considering and they're just really well developed well thought through so before we start with let's just talk about why do these type of products evan and who is my target audience when you watch my watch my shows i do it actually for teachers who are interested in you know add in a little stem to a class ideal for parents at home who want to work with their kids and develop these and also for kids if you just want to watch it and get this product and work with me you can do that very simple because with the princeton t v shows you can actually come back again so you see what i have ordered come back and watch it again and we can build together so let's start with this rather and why i like it i think  it's a i've done a couple of the salt water type cars and the reason they're considered salt water cars is because that is actually the fuel cell is actually salt water what will we get to that point all part you notice it's very nice and it's a good thing to actually introduce for anyone who's into the elements in your in chemistry or teach about different elements and you want to just focus on just you know something that's more hands on more stem which you know kopassus everything this is something you can do because you can build a few sell out of that so we're going to build it later and hopefully we'll get to today if not we'll get to it at our next our next show so this is what it looks like it's a pretty nice belt if you look at this the wheels are really easy like i said there their products are really great and i really like  and i've been working with them for years now so this one i just started i think last year i got the first one and these are new anyway so i've used to do the little salt water car which is nice too it's a very easy in this one is a more complex in the gear design so that while i like it so it's very simple car and there's a little got use if you you know you don't do things right and i just did one here and they thought that you can you can tell how the gears work together and we're going to start so let me put this right here so you know what we're building and let's look at this so again remember my boxes very simple you get why you push down on the tape is and to i think you have me down madison put it up here so i'm going to tear this open by the still easy for me to put stuff back and forth and so what you should do is actually have your scissors out so when you're showing your students or if you are still in building it you want to cut this and i haven't in my purse which is down there so ok so they have panels as always we you know we work in that they would build up the panels which i really like because it helps with the organization component and never never never never just take everything out when you're buildings up to because that is a for us actually avenue to disaster in the simple build because it's easier if you fall in the instructions and i do go through and look at instructions a lot when i do my first building after that i usually don't because there's usually problems as i go along there's something there is missing or something that i did not look at correctly so when we build this i'm going to sometime you see me look at the structure make sure i have everything right  and bill this right so this is up for us panel one take out when i reference b panel this is b the white panels b and you can see that it has the body here it has a couple of gears so this is a patent i put aside and these are the stickers that you put on it and i'm not i have to say go in and actually use the stickers i never use and what my kids they take them home they can add them to it i don't do it but it's nice if you want to then aside but if you're working at home or you're working with your students are your parent working with your kids you should actually use that and like i said cut it and put your stuff back get it but since we need everything available for us to do this we are going to leave it there now the thing about these which is always interesting is they have a so you can just hear it and that never happens when i'm doing it because i always felt like i said i'll just places that i don't have masses and i have to really tear it so let's get this open and we're going electronic so we didn't do it as a separate motor one but i do have a nice project for that but for now let's just talk about what this is this bag has a little small motor here and we're going to start with that it has year positive in your neck of the has a swipe here and has a yellow here and there has to polls that we've and i need so put this aside and also this little this because this is a salt water car that is the fuel that we're going to use to get the two pieces of two elements a chemical reaction to the two elements to get electrons moving so that's this is actually what you use with the salt water and this is a no other axle for the wheels and it has to be years on it itself we are and then this is a battery because it has a magnesium strip i think a carbon strip which is not my cars here it is and it has some tissue we're going to put the water on so i'm going to actually put everything back in here so i don't lose it and i'll tell my kids that so if you're working at home and you are and organized like i tend to be sometimes just put everything back up ok so first start we going to do is we are actually going to go to battle and we are gone to start with battery in the battery component that we want to do is want to take off it is number one on this sheet in this blue sheet is actually a so we want to take off a one so what you do it's again it's really easy to take these  off the only difficult comes is some time this little pieces of plastic that that is a part of the panel that you know attached to whatever you're taking now you want to keep it clean especially with the gears because if you have a piece taken out of here that year it's not going to rotate well so you want to work on that ok so we took out one and as a first thing and we want to take out our battery now the thing with this  you have to watch the way you put the molder niceness i said barry i mean motor you put the motor in so we want to take that out and also take out our little yellow pinion gear which is in that bag that has orange and white and again if you had scissors you will cut this and since i don't i'm going to use these tweezers and i have tweezers when i am teaching and it's always good to to start so when you started this you should have scissors which i have in my purse sorry and i did bring and i just realized that because i did that actually let them in for a side note to take them out but i didn't you should have scissors i always used to users because it's easier for kids to work where and they're in this sense well so those are the three things i usually have with this i have extra parts too because we tend to lose pieces but that's ok i have them here so hopefully i don't lose anything but no guarantee so let's take out the yellow so we have a little yellow pinion gear and we have a nice small motor and this is one of the things when you're doing something that's alternative energy like this really is salt water it's not a regular battery this is a better religion going to make in a tissue which it will have salt water on it and magnesium and the connector of the of the the motor the to connect a positive the negative they're going to attach which is kind of a negative and that's how you get the connection and the salt water is in between so that kind of gets economical reaction and you're notice when you look at your magnesium strip it actually  kind of corrode so that's what i talk more about later or maybe not but just let you know ok so first thing you want to do is you have put this yellow gear you want to touch it to the motor and if you look at the yellow gear it's a very small thing in here and it has the teeth of the gears on one side and on the other side is kind of like just a circle where planes are full so you want to make sure that you put this on with a circle component there is actually touch and the motor itself i'm not really touching but close to the motor because the other part of the teeth is has to be out because the gears on which you do is you want to mesh gears together because you've got  you know you have to measure get together like this so the force of one tooth here it pushes on the other here so the gears always have to go together so if you were to do it the other way with the circle they don't work so you just want to watch that so the easy way to do that and i have my kids do is just put it on a table and if you're doing this at home and just press it in and is president wanna you know very simple and one thing i do want to make sure is i said that circle part of friction and it's not going to work or it's going to go very slowly with them some issues so and then also you know you need it out because you want it to you want the years to come together and if it's too far in the summer some problems so you want to push it out to the tip you should still see the silver x o of the motor but you want to push it out a little bit so now we're going to put this and i was saying about this when you put in you have to be careful because when you look at this little piece  there is one that's higher than the other and one short and so that means in this world because i always get it mixed up and i hate to do that is that the black actually goes in the high side in the red and goes  the low side and so you want to watch that because you mix it up then you know you have some problems with it you're it may go backwards or may not go at all so this whole thing for  e other pieces of bourbon go into this holder which is really the holder for the contact so as i said the black piece and the way this works is you have to have the space and i was going to go into this so we have to have make sure we have a face in the correct way so what i do with this and i'm looking over here because i always tend to sometimes wrong but i'm doing it right now so if you notice this little slot in it in the back and in the front this is kind of the back of the slot should facing you when you're doing this so if you have this in your hand you're trying to put this and you want to make sure you do correctly and it's easy to make this one little mistake and then have problems throughout but and it's not really through our i should say when you start  it's not working correctly and it should be just didn't do this right so the slots that you see you want to have a face in you when we do this is just focusing your hand have a slot facing you and if you look at this is my right side are right that i have a short in my left side i have the along and of course i'm facing you so your face at me so kind of backwards but just make sure the slots are facing you when you're doing this and then what you want to do is you want to put the black in the the black wire the negative wire and you want to put that inside smooth put that into the high end which is your negative right so we're going to take this kind of twist a little bit and you want to have the space and forwards because this is going to go into your motor kind of your body kind of like this so you want to if you take this and you have the slots facing you you want to take the black wire and you want to put it in the high end and you just see however this is pre designed for so we know just knowing is that the part that is actually attached to this metal is another is a wire piece from this this black wire it's not the plastic component th it's not bad to talk about it but sometime i tend to go off and i try not to do that because then i don't complete the zone time and this time i like i said my take to class two shows or three depended so we're going to push this  and push this all the way and now you want to go through and just make sure this is pushed in like this if you look at the back here you can see that it goes down and again this is the high end so the black one when the high in its face and the slots  face at me and this is facing outwards because when we put it in and has the work like that then you take the red one and you get a put in the other side which is the short and right is a short in that high in black and the red in is a short and  runner and if this is not done correctly then you have problems right so we want to make sure that is and the reason we know is the power here again this is a task of attaching the power source which is the better we're making the fuel cell battery so let's just put the you think so again this is this helps me with the plastic so i just go necklet this some other kids can break it but if you are somebody at home and you want to see if you have something a parent can help you out you know  that if you pinzon agent one of the things they do also actually here have or here somewhere is aging is a plus but i do work with younger kids but what i try to do is make sure some of the pieces that require older kid to be older i do or help them with a make sure it doesn't do something that should and so for example this is one of things you have to be careful because sometimes these little plastic pieces can cut you which is interest are to the body it's this is one in three and they're actually different because you're going to work with one so you want to make sure you get the right one out because there's different building this you want to work with them and make sure that they that that doesn't occur so you want to really work with them and then you want them to understand because some time when they have their ages or kids to build certain things it's easier it's better to follow that because there's a lot of little pieces to it and then little hands sometimes lose them that's why organization is a big key here but i have to say i'd start working with ken regardless and i had some of my kids who are young who have no problem keeping stuff and together are building these items but they've been with me for you know for a while so they're good at that so we'll take this piece and we will now add this now this is actually going to we're going to attach this here but then the reason this is act tax here it's right here so this little hole here if you can see if you can see that that's the gear is actually on go and then you got to put it face in down think one of things i should do is more product reviews because there's so many great products out there and it is sad that we try to reinvent the wheel when you know but there's nothing wrong with the invent new things but i think there's a lot of great you know people have a lot of great ideas i am fortunately have a lot of great ideas that i haven't anything with sell but because i would really like to do something similar spider robot and make everything a little bitter a little hands but that's a different story so here ok so that's very simple and of course if i've got it wrong we will know that later right there's something ok so let's move on to the next part so we did that we attach those two pieces together want to have a face in like this you can put it like this you put this in like this now one of the things they want you to do is actually be careful with the wires so you need to take the wire the wires and you want to put these down and if you notice just little if you really just look at this little clips or not cheers in here that you can put the wire in all and that's one reason i have the tweezers too and the black should be why should be facing out facing you so you put this in so take it we we know we come here we have to put this them and then we now we want to secure the wires so they're not all over the place we don't want to get the wires tangled up in the gears you want to secure them so by i use because i think it's an easy thing for kids to use and i'm expensive for you to have a bunch of them there's a lot of things you can do with tweezers so what you do here should just take the tweezers and you just move the wires just in these will not just put them in the little not just so it kind of secure of them so you want to just stick to the wires down that way and i'm doing this for you guys so you see and it's not as easy as i said when i do it at home by myself and i'm not on the  that piece we just did so again it's easy to do these with tweezers i recommend you keep tweezers when you do this and you find out that you know you can use them a lot of things so it's a it's very simple you just push that down so when you check this wire system so you don't want to have the wire sticking out like this so use your tweezers to put it in and what i should have done is actually pushed it up a little bit on this and just pushed up this little bit so there's no wires sticking out because you don't want them to get tangled so it's actually two minutes and i have to go and i'm going to start finishes up a few minutes my next show so i say they go and just push it down so we will finish this up again and on that show so come back and you will see how to build this baja one of which is i think a great teaching tool too when you're in the class
