Like a watermelon and dozens and dozens of rubber bands.
With these added measurements i may have been able to provide some statistics and a more precise hypothesis about how many rubber bands would explode a pumpkin.

Dr rob certainly has and he s destroyed many melons seeking the answer.
In this exploding watermelon science experiment you will observe the potential energy of a stretched out rubberband convert to kinetic energy as the rubberband retracts back to its original size.
Https youtu be zzfka1 x2ta today we try to blow up a watermelon with rubberbands.
Thankfully they brought 500 elastic bands.
If you only put a hundred or so rubber bands on a watermelon it isn t going to make it explode but over time it may cause it to split because the force on the rind has changed and continues to do so as the rubber bands want to go back to their original shape.

This event culminated during national science week 2020 with over 300 schools taking part in one giant and somewhat messy science experiment.
Gav and dan forgot to bring a knife to the picnic.
This movement from potential to kinetic energy will in essence cut the watermelon in half and make the fruit appear to explode.

The rubber bands stretched around a watermelon not only increase the potential energy of the rubber band but also of the watermelon.
