Whats that sound? pop pop pop POP! CRACK! SNAP! BOOM! Thats the sound of my lovely feet popping bubblewrap and air-filled packaging bags. My pretty toes love finding the little bubbles and hearing them crack and pop. I even take a whole sheet of the little bubbles and demolish it by jumping up and down to create a cacophonous sound of pops! Finally, I take a bunch of those air-filled packaging bags and make big, loud, booming noises as I blow them open with pressure from my feet!
