Did you know that today is Bubble Wrap Appreciation Day? It is. And whether or not this is a holiday drummed up by the fat cats in the bubble wrap industry, we feel it deserved your attention.

Think a sheet of air ravioli. Popping said bubbles is highly addictive. For bubble wrap-popping simulated fun, check out this this Flash site, or this one to get your pop on.
