Gelli Baff (Jelly Bath)

Oh, to be a kid again:

Gelli Baff is a powder that you pour into your kid's tub to turn the water into colored slime. The goo is a completely harmless powder that soaks up 400 times it's own weight in water. When the fun's all done add the dissolver packet and the goo disappears.

Too bad it's only available in Great Britain.
