I got some tight bubble wrap packaging in my recent amazon presents package and I just couldn't resist taking my bare feet to them. With my burgundy toenail polish and perfect size 10 feet I start delicately stepping on the bubbles, testing their strength. I find they are tough to pop so I have to manipulate the plastic with the soles of my feet until I stomp and trample them till they make a loud popping sound, releasing their air. I crush them over and over until all the air pockets are gone and then I take my toes to try to destroy the plastic fully and completely.
