Fruit ninja in oh, the idea that a human being can throw a playing card with this kind of power and accuracy is insane to me. Look at that and while throwing cards isn't necessarily my strong suit, i can design and build stuff. So i made the world's first deadly powerful playing card machine gun. So i'm going to give you a quick overview of the design and performance of my machine and then to really test it out.

I'm going to go head-to-head man versus machine in a series of challenges against the best card thrower in the world. Here we go so to start off. You load a deck of cards in the bottom right here and then there's really two parts to the gun. First, you want to slide the cards forward, one at a time from the top of the deck, underneath that's what this belt and pulley are for, and by turning this variable resistor, we can adjust the feed speed and then, for the second part, you've got this main Wheel with o-rings stretched around that's attached to this brushless dc motor, the cards are pushed under the wheel and it contacts on the left side and it spins them out underneath like this.

It works because there's a gap under the spinning wheel, that's just barely smaller than the thickness of a single card and to build it as usual. First, we started in cad, then machine, the main body out of aluminum c channel. After that, it was just a matter of putting it together and running a lot of tests, and so this is what it looks like running in single shot mode and then machine gun mode and then robin hood mode, and perhaps my favorite part is if you want Extra stability - you just push this button. I think i'm happy enough with how it's performing at this point.

So now it's time for the real test, and to do that, i track down a man who could throw a playing card through just about anything rick smith jr. So how many world records do you hold rick? I hold three guinness book world records, throwing a playing card, the farthest 72 yards 92 miles an hour the highest and considered the most accurate all right. So in order to objectively test how good this really is. I am challenging the best.

The human race has to offer three rounds, man versus machine. Let's do this. This is like a metaphor yeah. It is how do you feel with all of humanity's hopes and dreams resting squarely on your shoulders, really worried on this? This is pretty impressive, i will say it looks, i think, a little more intimidating than it is.

This is highly over engineered. Is it no? No, i think so. Let's go all right. Okay round one man versus machine okay, how many cards can you get in the styrofoam in six seconds? Six seconds got plenty of strength.

I got this. This is a machine gun, start uh time, one two, three, four: five: six: seven, eight, nine, nine and six seconds i'll time you ready! Well. I didn't want to introduce this yet just right out of the gate. But what is that? Go? Yeah.

8. 9. 10. 11.

12., even though i beat him in the first of our three rounds, rick said he'd show me a few of his trick. Shots! Yes, so round! Two. Are you ready right now? I just want to say machines. One humanity, zero! Oh well! This is about accuracy.

Is your machine accurate is, it is fast, oh, even more accurate than it is fast, but i'll prove that to you, i throw the olive up one chance, one chance slice it clean through. I got it oh long ways wow completely in half. Am i nervous? No. All right time for the machine, let's go! Oh jeez, i mean that was close at all.

There's got to be something there. You switched the olives. I did not whatever fine 1-1. I guess.

Oh, my god. That scared me. I want you to think of a playing card, any playing card on that we've been playing with cards all day, long awesome name that card now ace of spades. That's a common card! You sure you want that card yeah all right! This is an ace of swords.

That's my business card. I don't know why that's in there, but you really want the ace of spades. You can change it if you'd like i don't want you to be able to. I do want to change.

Well, you're, changing it yeah! Oh, you said it all. Right, what are you changing it to three of clubs? I knew he would look at this. Look, look. Look.

You look through the cards like this slowly, look, look, look you'll, see that one card and one card only is it happens to be the three of clubs. Stop was that it? Oh, why so cool my mind just broke, i hate you so much, i'm so sorry, the world is no longer true, it's witchcraft and to help calm, my very troubled mind. Before the final showdown. I decided.

We should blow some stuff up. You guys ready, and the physics at play here is pretty straightforward. If you've ever put your hand out the window of a car, you know what happens if you barely angle it up or down so to fly fast. You want to be perfectly level, there's the sweet spot right in the middle.

When i covered the science of the perfect rock skip in another video. We talked about how spinning things are more stable because of newton's first law, so rick really flicks his wrist to maximize the card rotation which keeps it stable and level slicing through the air much longer than anyone else on the planet, all right, rick, smith, jr, all Right mark rover: this is the last competition. Okay. What are we doing? First, one to stick it in the watermelon wins that should be easy.

One try, there's uh the one catch the cool little twist is you have to shoot under the waterfall? Okay, all right so you're gon na give us a countdown i'll count down this. Is it man versus machine? Is it this over engineered nasal piece of junk or the collegiate baseball? Throwing guinness world record card thrower place your bets in the comments below just don't forget to take this into consideration, when i count to three on three yep, and so while the robot uprising is undeniably marching closer every day, at least for the time being, rick smith Jr has our back. If you want to learn how to throw cards like rick smith jr, he actually put up a tutorial video on his channel. It's actually a super teachable skill, because i started out like this and less than five minutes later.

I was doing this. So go check that out and sub his channel for more cool magic and card trick shots rick. Could we go maybe a little thinner on those slices pal hard through just about anything? I wanted another go at it. Sorry, i'm 2000! You know i'm too fast.
