Here is where I got my rubber bands

Safety: Use Safety glasses and do not look directly over the watermelon as it is going to shoot up like a rocket!
This demonstrated show the difference between potential and kinetic energy by exploding a watermelon with rubber bands.
You will need a watermelon, 300-400 rubber bands, some Safety glasses and do this outside. Mom's don't think its funny doing this experiment indoors. : )
I used size 64 rubber bands, which stretch easily to 17 inches. 3 1/2 x 1/4 (88.9 mm x 6.4mm)

Put your melon on a table. We use a cardboard box to hold it up right. You will need two volunteers for the experiment as its little hard to pull the rubber band over the melon by your self. I would recommend one at a time start slipping rubber bands around it. You want to make a big belt of rubber bands around the melon’s middle, so just keep stacking them on top of each other.
After a few minutes of applying rubber bands, pause and take a look at your melon. Is it still the same shape? You may start to see the top and bottom of the melon bulge out around the rubber bands. It starts to look like the number 8 in the middle.
As we stretch the rubber bands out to get them around the melon. But once they’re in place, they start to contract, squeezing the melon. All that pressure from the outside is forcing the inside of the watermelon to find some place else to go, so it’s will start to bulge. Looks like the number 8 in the middle.
Rubber bands are a great example of potential energy. Potential energy is energy that is stored up, not being used, just waiting to be unleashed.
Think about when you stretch a rubber band, then let go and it snaps back. It’s using up its potential energy.
When potential energy is used up, it becomes kinetic energy-energy in motion. So right now all those rubber bands around the watermelon are stretched out and full of potential energy, ready to snap back. and guess whats going to happen to the melon in their way?
Keep adding rubber bands and eventually the strength of the rubber bands’ potential energy will put enough force on the watermelon to squeeze the top and bottom of the melon apart. The rubber bands will cut through the melon and contract. What do you expect the melon to do?
Once your melon explodes, the rubber bands will have snapped back and used up their potential energy for now.

ha ha... the kids liked that one! Luca would LOVE that kind of science! ha ha...
Yes Luca would love it. Its a favorite and fun every time I do it. : ) thanks Ken
Your determination tho. I watched you like 3.5 years back, was shocked and really in nostalgia to see you still uploading.
Hi Akshar, I run science night at 5 of my local elementary schools for the last 16 years. I'm always trying new experiments for the schools and post here so the parents can do them with their children. Now my neighbors grandkids come over and have fun doing experiments with them. I love science and will continue to post until its not fun anymore. : ) thanks for watching thx Ken
@@KidsFunScience awww love you sir, resepct ✨
Wow very nice experiment. Keep up the great work.
Wow! So cool!
Great job! My congratulations to you from me. I wish you good news and new interesting events. Good luck developing your channel 👍😍😁
Incredible this experiment, I had never seen it explode like this! Thanks friend have a nice weekend
Wooahh- that was quite some explosion 🐱🚀- so the force applied per unit area resulted in increasing pressure due to reduction in area causing the explosion.
Yikes! LOL I would be stepping back.
Exactly! I have done this many times and I still shook the camera when it exploded. lol Never get tired of this experiment. thanks
Awesome!! 😁😄
So fun you guys, amazing channel, for grown up and kids alike! I am always intrigued to see what happens! 417 yeyy! amazing!!
Yes one of my all time favorite experiments. thanks Ken
yesssss. This is awesome
One of my favorites : ) thanks Ken
This is cool. I did with my learners in grade 2. Awesome 🇿🇦🇿🇦🇿🇦
Hi zukisasweleni2027, yes one of my favorite experiments. Thanks for watching
wow! cool experiment!💥
Wow👌, Amazing
Good Morning Nived K.P, thank you as this is one of my favorite experiments. Thanks Ken
Thank a lot, I'm deeply appreciate you, sincerely pray for your luck!!!
Wow Amazing 😉
Thank you this was a summer favorite. : )
Good .
We had so much fun doing this experiment. Thanks Ken
das ist cool
