Nate. Yeah. shoot. We're back with six magic tricks you can only pull off with science. And despite possessing magic abilities myself, right back. got you. All right. it's ScienceBob that's going to be showing me six magic tricks I've never seen before and we'll try and see if we can figure out how we did them. Would you blow that up for me? Sure. Trick number one started with balloon do know this trick. and tune. That was great. I'm going to see if can cast spell on it and get it to pop. What? Scared me so much. You just made it pop without touching it. Correct. Got another balloon. Let's see if we can do it again. What just happened? Wait, blow dart? That was science. Okay, Bob. have hypothesis. There's something on your fingers. They were glistening little bit. So you caught that. Power of observation, the first step in the scientific method. So, you were right. My fingers were glistening cuz had sprayed Orange peel juice? Orange peel juice. Orange peel juice has little something called lemonene lemonene lemonene lemonene Wolfio. It is lemonene. That's interesting. would have never guessed that it was lemonene. So, you get that out of an orange peel. Balloons are made out of latex, which actually comes from tree. It's natural material. And it's the chemical in orange peels actually has chemical reaction and breaks down the latex. So just go ahead, give it little spray on there. No way. don't like loud sounds. WALLY. Just dip my fingers in there see. and gave little pish. That was very, very cool. And I've always said that lemonene smells delicious. We were only on our second trick and CrunchLabs was already feeling more magical. Wow. Always wanted to do that. There's little wand test that they don't show you in Harry Potter where you poke hole through bottle like that and that's going to leak obviously. But just want to see just like if you have little wave and let's see if you can stop it. H2O stoppicus. Wow. Now I'll take the wand away. H2O goicus. yeah. That's pretty good. Stoppicus? that's pretty impressive. What if just say abracadabra? That works, too. Please stop. Please go. Literally anything works. Use the force. Wow. All right. feel like you could figure this one out. feel like something's going on up top. My guess would be there is hole in the top. And so then when you remove your finger, it's going to equalize the air pressure and push it out. If you have it in there, there's vacuum and it would keep the water on. So you're saying if take my finger off It would go Cuz there's little hole in the top. All did was before the trick, poked little hole with the pin. And as soon as you poke that, that's going to go and just like you said, we got equal air pressure, created vacuum and it stopped. Wow. So you just like barely shifted off. Goicus. Stoppicus. Wow, cool, Bob. And then if you hold it, then squeeze. sorry. Sorry. And if that wasn't enough liquid, trick number three involved three bottled beverages, brown paper bag, and an important message about recycling. Here CrunchLabs, we like to stay hydrated. This is true. And we like to recycle. True. We have plastic recycling and then we have paper recycling. But here we don't have mixed recycling. So then you just have to use magic. And that is where magic comes in very handy. What just happened? Magic. hold on second. Here's an observation have. You used this bottle versus the other ones. observed the difference between these is this has bigger label. Am sniffing up the right tree, Bob? You are. Keep going. There's no way there's an actual full plastic bottle in there. What think we might find is there is crushed up label. You appear like bottle. Well done. Yeah. And with the help of bear, you can pull off this trick, too, by carefully cutting one vertical line down the label of any bottle with the full-sized wrapper. it in the bag and then the trick is ready to go. voila. Trick number four involved two huge rings, two pull chains, and challenge from ScienceBob. You're going to put it up through the pull chain and then get the ring onto the pull chain. All right, so we're just going to drop it on three. One, two, three. Like that. no, no, no. You hit the table. Try again, I'll show you. You ready? Here we go. Ring goes up Yeah. and then you just drop it. And then you just drop. Okay, maybe here, you can use mine. Let me just check see if yours is no good. No, it is good. Okay, think saw what you did there. Hold on. Hold on. Hold on. Let me think about it. Suddenly was struck with vision from my past. It's lark's head. know that knot from Boy Scouts. lark's head is simple symmetrical knot that had made countless times as Boy Scout. we go. And now my childhood training was kicking in. Ring goes up AND SHALL we take look at how this works? Yes. All right. ScienceBob explained that all it takes to make this knot is spin and Newton's laws. So when you drop the ring, you give it little twist so that it flips over. That's called rotational momentum and then gravity takes care of the rest. Flips it around. That's tried that All right. So there we go. And it didn't mean much to Bob. It's kind of easy. But this meant the world to me cuz was now one step closer to getting the metal work merit badge that had evaded me since was in seventh grade. Now Bob, know you're technically the official magician here because you have the coat. Whatever, I've got little magic trick of my own. And now you might be thinking there's string there and if that's true, how can do this or this or this or even Oops. Now of course, if you're already CrunchLabs Build Box subscriber, you know this is nothing more than the Coanda effect at work. Now what's really cool, Bob, is like tilt this, it does it off to the side. That really looks like magic. beauty here is we can have face-off. Red versus blue. 3 2 1 GO. YES! WHAT? WIN. WHAT the heck? Not cool, Bob. Trick number five seemed little less elegant because it only took an empty soda can. What lot of people don't know is you can automatically refill cans. First step is you just get the top and if you just rub it really hard, take it that off, then it seals itself back up. Of course, you need the soda. All you guys got to do is shake it and then Bleh. That's pepper. love it. Okay, I've got nothing here, Bob. Powers of observation are not working. Turns out you actually do need few more things for this trick. Most importantly, small piece of black paper to create an optical illusion that totally got me. can't believe fell for that. It looks so obvious now. this up, poke small hole near the top of the can using push pin. Nate. That was supposed to go on, Mark. Then you need to get enough liquid out of the can to be able to crush it little bit. And finally, stick the black piece of paper to the top of the can so it looks like the can's open. did have little like double-stick tape on my thumb. So when you rub it, it came off and now you've covered this with your finger. Right. Shake it. Whoa, it's full. open it. There you go. Refillable can. People don't know about that. So that's thanks to the science of Optical illusion there and then air pressure. Love it. And for Bob's sixth and final trick, he brought nothing. have no props, but I'm hoping you might. need some money. Dollar bill, five dollar bill, ten dollar bill, hundred dollar bill. Will get this back? We'll find out. Okay. That is real. Well, so I'm just going to crumple this up and we're going to put that on there. And I'm going to put your hand right about there. And want you to just grab that bill as fast as you can. Easy. Ready? One, two, three. Pretty fast. Thank you. Now, I'm going to put my hand up here. Okay. I'm going to try to grab that before you can. As soon as you see my hand go, you can go. Okay. So you just have to wait. As soon as you see my hand move, I'll What the heck? Did you like math that out? No. This works because what do know that you don't? When you're going to go. When I'm going to go. Even though my hand was so much closer to the dollar bill, Bob actually had much less to do to get there than did. ScienceBob just had to decide when he was going to move. But my eyes had to perceive the moment that Bob's hand chose to move and then send the signal to my arm to then choose to move. And all these moments, which might seem instantaneous to us, still take time and end up giving Bob huge advantage that would be absolutely impossible for me to Think you can do it second time? Yeah, can. Actually, this time would be different. And it was different. Not in the sense that my hand moved in time cuz it didn't, but in that Bob's hand just slapped the table and then missed the dollar bill. Bob. would have gotten it if missed the bill. It looks much worse in slow mo. Well, there's bunch more magic tricks for you, so go blow the minds of your friends and family using science. Bob! Sorry.
