I've done the paintbrush into the drink too many times to count, and one worse: Instant Mold (If you're not familiar, Instant Mold is a clear rubbery material that softens when soaked in hot water. It can be pressed around small parts like helmets to make a mold and then filled with greenstuff to make a duplicate). Scalding hot *and* a floating residue of greenstuff, delicious!
