Hello everyone, Inventor 719 here and before we start the how-to video I would like to introduce you guys to my brand new purchase this I got used actually It's a micro 3d printer as you can see m3d. This is a 3d printer obviously I downloaded the software and I started playing around with it So hopefully you guys are gonna see it in my upcoming videos Let me know in the comments below what you want to see me make with it Has to be legal I can't make a real gun obviously, but I can do some fun little airsoft guns maybe inventions Whatever you want just let me know down below you'll see this shortly and anyway let's get started on the video So for today's video you're going to need a pellet gun Some BBs or pellets fire crackers and a lighter So the pellet gun we're using today is this Chinese one I got from a hawk shop It is fully wooden metal and it says it's 450 feet per second So it's pretty cheap it was like 40 bucks, which is the one I'm using in today's video. It's a Brake barrel spring powered gun. I wouldn't recommend doing this with any other more expensive gun or a gas powered or Luchx pellet or airsoft gun, but that's the one we're gonna be using today and We also of course will need fire crackers for this experiment. Here's these two I have here just to show you guys Basically these are your standard issue. They're big and red they're not large, but they're regular size and these are the tinier ones Now the red ones here I believe are around six millimeter Diameter which is the same size as an airsoft beady. These are too big for a pellet gun You want the smaller ones and they actually fit perfectly This is a 0.177 caliber pellet gun as you can see they fit perfectly just like that in the barrel So we're gonna go ahead and do a baseline test using the regular brake barrel action as you see break it in half pop it back in place The eBay one has trouble sometimes and then go ahead and shoot and We're gonna do that and then the firecracker and see how much more powerful it is So first things first for the baseline testing I'm gonna take one of these ball bearings turns out they're a little too small So I'm gonna go ahead and drop it in the lid of this tube of high-temp disc brake grease and all that allows me to do by mixing it around It's adds a nice little coating to the outside so that when I put it in the barrel It sits nicely instead of just rolling all the way through let's go ahead and Crack it closed and do a shooting test at this little tin can So there's the can it's actually a pretty heavy duty soup can so it's definitely not gonna go through it Might dent it pretty good though. So I'm gonna try and aim with no real sight Here we go firing in three two one Let's go check out the damage. Well, I stand mistaken the lube money to help seal it up real good We have an entry and an exit hole. Let's try the firecracker All right, so now for the firecracker test We're gonna start with the BB first so again BB in a little bit of grease Putting it in the barrel first. I'm gonna crack it in half to make it easier to load All right, there we go and now using the small firecracker. It's actually lightly lubed up to to make For easy penetration So go ahead and push it in the barrel all the way now Unfortunately the fuse has to be lit and then closed So this is gonna happen very quickly. So let's go ahead and with the shooting test So there's the can setup my gun is loaded and just because This might destroy my gun. I'm gonna be nice and close But if I miss I put up some plywood for another damaged test So basically I'm gonna light it close the barrel and point and probably less than a second So get ready because here goes the shooting test no countdown So I'm gonna be a little too focused already and here we go All right, I think I missed a little high here's another round loaded up. Let's try again I Hit the can let's go check it out All right, so there's the hole it made in the can entry and exit as you can see it's very similar to the one made by the spring powered BB anyway, so Definitely a pretty fast gun in both circumstances, but the firecracker even with just those small ones were pretty powerful Here's the shot where I missed there's where it entered the plywood and It didn't exit, but there's a crack where it hit it's gonna hard to see on the camera, but it I think just about made it past this Half-inch thick plywood Anyway, so there's a fun little thing if you have a crappy gun or even a steel pipe laying around to try I'm gonna try and get my chronograph out here It's in storage right now so we can do some actual chronographing to find the actual FPS So stay tuned for that if you're not subscribed Please subscribe for more experiments awesome videos again Let me know what you want to see with the 3d printer of course I want vacation so there's gonna be lots of cool videos coming up And my guns survived this test, which is also good So thank you everyone for watching.
