Essentially an advertisment for "Blendtec Blenders", nevertheless, despite its commercial motives, this site is quite a large amount of fun.
The premise is simple: you think of something, the people at Blendtec will see if they can get it to blend in one of their blenders. Videos so far include: an entire thanksgiving dinner, a can of coke (can included, obviously), golf balls, an iPod, a crowbar and a garden rake.
Videos are divided into "try this at home" and a "do not try this at home" categories.
