Made from a nickel-titanium alloy, and highly processed for electrical activation and long life, the thin black thread-like BioMetal acts as an artificial muscle. When powered, the BioMetal contracts. When power turns off, the BioMetal quickly cools and the wire extends again to its longer, starting length.

Aerogel - it holds six world records for physical properties and is nicknamed 'blue smoke' for its appearance; unsurprising since it is 99.8% air. Despite being used in the NASA Stardust and Mars Pathfinder missions, aerogels are not a recent invention and they were first prepared in 1931. It's also a great insulator - here are some wonderful photos of it in action.

Today at work I noticed we were running a little low on stickers, and mentioned that we didn't have enough of Mr. Yuk around. My poor, freakish coworkers had never seen or heard of the funny face from Pennsylvania. Although I seem to have doubts about how effective it is at steering young ones away from potentially deadly everyday items and other dangerous materials.
