Impulse and packaging bubbles

J loves popping all of our packaging bubbles (luckily for him, we do a lot of online shopping). He has experimented with the most efficient and satisfying way to pop the bubbles. One day, I decided to record his tactics:

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?
