Other uses for hair gel?

So I've acquired several bottles of hair gel. I don't use gel, and Jon will only use a very specific kind, of which these are not. Any ideas as to what non-hair use I could put it to?

Alternatively, if someone wants a crapload of gel, drop me a line and I'll send it all to you.

Actually, now that I'm on the subject, what should I do with a bunch of eyeshadow and lipstick I'm not going to use on my face? They've all been used at least once, and none of them are fancy brands, so I doubt anyone would want them, but I'd prefer not to just pitch it all. Thoughts?
