He figured out that popping works best with a quick jump on the bubble, but he had a hard time popping the bubbles with his hands? Why?
With jumping:
1. He gets all of his weight (and then some - biomechanics, yay!) on the bubble.
2. The time he exerts the force is short.
With his hands:
1. Not all of his weight is transferred to the bubble (ie, he's not doing a handstand on it). Some of his weight remains on the ground while his legs hold him up.
2. The time he exerts the force is a lot longer when he uses his hands (the bubble takes time to deforms before it pops).
What simple science experiments have you done this week?
My son loves them too. They are sun for almost all the senses.
