The Bubble Wrap Stomp

Uh! I marched straight out the back door because the house was getting boring! Right on the wooden porch steps, somebody dropped a big strip of clear plastic with tiny little air bubbles! I stepped on one with my shoe—SNAP! Uh! It popped like a tiny firecracker! So I started jumping with both feet up and down! POP! POP! CRACKLE! One bubble wouldn't burst, so I dropped down onto my knees and squished it with my thumb as hard as I could until—BAM! My whole arm shook! Now half the plastic is totally flat and dead, but I found three more fat bubbles hiding near the edge!
