Sorry about posting exactly what other people posted a day ago, I somehow always miss the first topic. I'm not very good at paying attention. :oops:

I'm skilled, aren't I :P ? On a different topic, here's something I'm pretty sure hasn't been posted yet: Test tube marshmallows

[edit]
i once did a xmas holidays job in a place that made panels for portable buildings for mining camps & similar needs.they were 2 sheets held together with an alloy outer frame & had an expanding foam injected into it at high pressure for a timed burst.
very impressive if let loose into someones tool box. [it sets to a hardness u can cut with a knife] but is going to keep expanding until the reaction finished. very good insulation too. [end edit]
cheers
