I love popping bubble wrap. At a summer job in college we used to roll over the bubbles with our office chairs. It was the most fantastic sound.
Bubble wrap makes a nice stress reliever and allows me to regress the days before responsibilities -- a career, a mortgage, etc. I don't get many things in bubble wrap any more. Schade! (bummer)
I was so excited to see this on Boing Boing! Although you can't roll over the Puchi Puchi Electronic Popping Bubble Wrap Toy with a chair, you still get that lovely sound. You can go to your happy place for just $7.20 (5.12 Euro). Available in five colors.
