 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the exploding watermelon. So I have some great neighbors that let me come over and use their grandkids. We do experiments about once a week and today we are going to explode a watermelon. Thank you for letting us use your backyard and not mine. So adult supervision and safety goggles are required. Okay so we're gonna blow up a watermelon. We are gonna blow up a watermelon. So right Ken the science dude is bringing the best for last before they go back to school next week and we are gonna blow up a watermelon. Yesterday was actually a national watermelon day so we missed it by a day but we're still celebrating. Perfect absolutely perfect. The watermelon we're gonna put rubber bands around it. Okay make a prediction out there whoever's watching how many rubber bands to be able to squeeze it all the way through to cut it in half to explode it. We got some guesses. A hundred and ninety. Hundred and thirteen. Hundred and thirteen. How many guess how many Parker. Two thousand. Two thousand. Papa. One ninety One ninety eight. Ken. I already know I've done this experiment before. Then we can't hear from him. What's happening is the potential energy is going to be squeezing it in and then when I get to that point when it's ready to burst the kinetic energy is going to bring it out and then kind of helps us cut the watermelon up for a seat. Awesome. Awesome. We got number sixty four size rubber bands here. Sixty nine. Sixty four. Sixty four. Okay it's already full surface. I had one ninety eight. I think you got about another eighty or ninety to go. Two hundred. Definitely got a figure going. So I slowed it down here in slow motion. We're starting to come up here. Here's four hundred and sixteen. You can see Papa backing up. He knows he sees a crack in it. He sees a little bit of liquid pumping out the sides as the rubber bands are squeezing that watermelon. It's about to explode any minute. When you see cracks in water coming out he knows better but P is not going to let that happen. Come on Papa come back one more. You can do it. So the boys decide hey they aren't coming in. We're doing number four hundred seventeen right here. P does get Papa to come in. I'm going to circle around to try to get a better view of this watermelon explosion as they're trying to put four eighteen on its boom. Explosion everywhere. Fifteen feet all around the yard. It's so thankful they use your there you are not mine. It's just watermelon everywhere. Success. Final count four hundred seventeen rubber bands. It's a success. Here it is in slow motion from a different angle. You just saw Papa was backing up. He sees a crack. He sees water coming out the top. He knows it's about to hit and right there you can see the rubber bands halfway cut through. I mean it's slicing that thing perfectly and one of the favorite shots right here that we freeze frame is how P's rubber band is catching the top of the watermelon which basically stopped it from launching about ten feet in the air. Though he did have watermelon pieces at least fifteen feet off to the side. I mean it was a complete mess and I know it was great that we did it in their backyard. What a fantastic fun science experiment. Thirteen! Thirteen! Too much of a mess does it? I was trying to get out of the way.
