Biodegradable packing peanuts are pretty much the coolest things ever invented. For those of you unfamiliar with this wonderful bastardization of nature, a demonstration:

They dissolve! They dissolve into a sticky, chunky mess and then dissolve into nothing and wash down the sink. It's kind of disgusting, but it's the most magical kind of disgusting.
