How many elastics does it take to explode a watermelon?
Herein, how many rubber bands does it take to cut a watermelon?
Good thing Gavin Free and Daniel Gruchy had time on their hands (guys like this often do) because it took them about 500 rubber bands in 20 minutes before the combined pressure created the visual dramatics. And they condensed it all for you.
Beside above, can you explode a watermelon with rubber bands?
The exploding watermelon stunt or exploding watermelon challenge involves wrapping rubber bands around a watermelon until the pressure of the rubber bands causes the watermelon to explode.
It appears that the force and pressure that a band of a large number of rubber bands wrapped around the middle of the watermelon can cause a crack in the rind of the watermelon under the rubber bands. The crack then propagates and ends up splitting the watermelon in 2 or more pieces.
