i went for the salt water car which i thought was really need at the end of the show and i was trying to get it in the hope i did and i think i did we built a little battery and the battery had a piece of carbon and also magnesium and what happened was we put salt water in between on the tissue to get like trans flowing from the magnesium to th as we go for these next couple of weeks i'm going to throw in probably a few battery experiments for you to test which gets and i think is a great thing because it's actually gone back to the periodic table talk about the elements talked about how many electrons are in the element there's so many things you can do with it that just and to talk about the battery and how you know we use batteries and kill kids are familiar with it so such a great great experiment to do now what i'm using is this kit that i found years ago and i have to say the company who actually was selling these actually sell them in japan so they're no longer in the us but i did look on amazon amazon still has a few of them and i have some i think on my website i'm not sure if i've sold out but i i think i still have a few but they're really really good if you don't have to use this kit you can just use the items so i use it to do the same thing so this is actually  a battery kit so we're going to use that's all very neat so let's start the experiment so we're going to do first is this his i think the holder which is nice and if you don't have this at home you just get a cup and on this they have the springs which i thought were you know a pretty great idea so you don't have to do that either you can just you know as you use them allocate the clippers it's really up to you but the goal is to get the material elements that i'm going to be use in so that's this is a couple going to use it and i am what we're going to try to do is we're going to use this is one reason i really like this experiment this is a little music box and when you when you get a little bit electricity there comes a little voltage the current that flows in here you hear a sound you hear like a little music and i can't remember what it was so you can tell me we're going to use this and let me get what we need out here of course our red and black wires so let's put that out one try to put everything here and do it in this area and i'll get to sidetracked as you know sometime i do and is that the the flow is going to be from the thing to the copper you know transfer that little hole that has twenty nine we're trying to do is come try to take from the zinc so it's going to go around the so what we need to do to get the flow go in and again if you think about literacy like you think about water in a pipe and you have a current flowing in if the pipe is just standing still and this nothing happens with the water in the pipes you need some something to get that movement happening something to started and then this in the pipe water it's usually some type of little pressure that you have them in the same thing applies to the electricity and currents and you have the amps go in but the voters actually they have like i have a cold i don't mean to do that so what we're going to do is we're going to use a couple of things and i have here for us to try to some may work some may not apple cider vinegar we're going to try one with that to see how it works and also you know the stronger the acid is we should get better sound it also get more voted so we're going to test that out and see i also have vitamin water which i think probably work better but i have this in my cabinets i brought that and i have these electrolytes that you add to your water what direction really really really good and her really nice to use in this experiment i'm going to put one in there and of course use that so we have four things to do let's go we don't have too long so i don't want to rush but let's see how we work at this working out what you do with this and this is why i love this but again you don't need this it's very something that's put together it's easy to use but you can use a cup and alligator clippers you can buy copper you can buy think and you can do the same thing i'm doing with this so i'm going to use this so what i'm going to do is i'm a poor little depending on the sound we get we can actually increase it and see what happens but it's a great experiment just to teach the kids how batteries work and how you get the electricity that works up with this and the reason i like it because again it was easy you just put the zinc a want and you put it in the little spring which is pretty nice where they have it set up and i really hate the fact that they went out of well i don't know if they went so much out of business if don't sell in the u s because they still sell in japan and they have a  this company actually have a lot of great need things so maybe one of these days they will come back if not you can still do this like i said with cup and just buy the material the springs the good  think with you had kids working with it it's easy for them to see you want to make sure that the the the metals don't actually touch each other to you see has a little space in between so we have it in there you can see it in the because the flow is going to actually from the zinc to the copper and then i'm going to know this has not that much again remember in the first class i told you that you have to make sure that you attach metal to metal not here and the first thing was we're going to try to say now i have couple of these the great thing about these are they nice they make it sound a bad thing about these it's there they don't actually take a lot of boating just a little bit too much will blow him out so i had several of them throughout the years and i'm down to a few of them let's i think you heard something and you birthday right i knew it was something for me it so we know right now the way this works electrons are flowing from algae all the way to the copper so they kind of go around the circle here now pretty good right so let's actually look at it now and see if it tells us and i do have a pin so i'm going to write down so i remember because i tell you i will not remember what the voters was so let's say this is how apple cider vinegar and  and it's probably not the be any more than somebody less than one because first of all that could you know you can blow that out because it doesn't use a lot of voltage so so again astride it now i did bring some of them to why one of the things when you're doing this you have to be careful same thing i don't know if you remember when i was doing the salt water car and if any of you actually purchased that which i love because i think it's such a great i actually love that hit because not only do you kids learn about motors and years they learn about actually how to create a battery any how the alternative energy works and i think that is so neat but if now the only thing is i'm not really good with this because really you want to kind of rants about so we're going to do that too and we're going to try something different and i know i actually haven't tried this in the should have i think a little bit  so let's do the same thing we just did this is a zinc on our a negative and went to the copper is going up positive and again i think i do like this but probably easy if i just stop this said with my alligator clip but i'm kind of partial to this kit and i know it's are not out there for you to buy you say why am i showing you this because you can do something very similar ok now the first thing we're going to experiments which i may actually not get to but that's ok if we don't because again all you need to do is get the and you know one  it's working it's not playing the song so i don't know if they have to act in the low to do that which is interesting so we know it works we know and we can use it to have a flow which oh actually i was wrong it had more its point nine five seven so we didn't actually get the song and it just made the noise and it's more than the apple cider something for you guys to try at home it would be fun for your kids to try different things and i have point was point nine five eight because nothing showing up  now ok so we are going to go to the next thing i think we have we have enough time and i have four items ok so same thing take this off and this time i'm not going to i'm going to try to wipe the this stuff but wipe it off i so far i like the apple cider that are going better because you actually could hear the song have actually brought salt two but let's do the limb is right it's acid which is actually similar to our vinegar so i'm going to squeeze in here and i'm not going to use i'm not going to use as much as i actually a really good thing to do you can actually stick to the pieces of metal actually in limit and tried that way too which it acts a great thing to do water when it's put enough in here that we get to a point where hopefully this overall  what two thirds of acid one time water no water is up to you a lot of things you do when you're working with kids with this and this is what i'm going to be going into i think i'm going to start in the fall doing my whole series of that and how i hear somethin not that much you know i have another one the mrs my other i did ok i'm looking around to see if i have way over here i'm gonna try this one for a while because i can hear bare i barely hear anything and i thought the women would actually be better but maybe i didn't have enough if it's that more lemon juice eight eight or so we really didn't hear that much with point eight four so again that's another thing you're doing with your kids you can just and i these are such great ways to test out that i wish i think i wanted amazon has a clue i really didn't look and see if they have those i know they have a feel these and they come with that so that be great ok so our last thing we're going to do is we're going to test out and we're going to talk a little bit about what you would do if you're at home doing this  actually i started doing classes on our school so if you're at home and you want to join my classes you can go to out school enjoy my classes because i'm going to be doing summer camps when that really camp summer richmond programs and everything online for my kids who are not in this area who still want to have a lot of fun doing construction stand so our last thing we're going to try to do well you know what we have enough time for both of these so let's let's do this and i limit my how much i'm creating because this is filling up so that's why i didn't do as much a lemon juice i probably should have started off with actually doing a and you know that's one of the things we do experiments and you w which kids make sure you actually do you measure it out better than this because in a sea easier experiment the kids understand what the changes are so let's do a little bit not too much  it there this a few minutes to see what happens and again i think this has a really nice flavor for prepared so you should use it for that and also good if things experiment when you experiment with kids you try as many things as possible and so they see the difference but again below different than what i did when i share the released that they started off measuring my cup and have a number put a piece of tape on and which i'm probably them in they'll put a piece of tape of how much you want to in made sounds but it didn't actually there was a problem with the the sound we didn't hear the happy birthday song so the lead tronics that it needed either we gave it too much in it which is more wasn't that much it could also be i could have we had problems with these two so we tried it again ok so let's take this off and i have two minutes i have to go so i'm sorry guys what i want to do is actually combine everything and see what we get and i think i'm going to do that in my next one before i start my second second class i want to thank you so much for watching me all construct
