Does anyone know what I could use to make the water for bobbing look cloudy? kinda like soapy water? I want to put some glowsticks in the tub to make it look eerie, but I don't want to have some bad tasting or harmful stuff.
Be sure not to let it get warm and spoil (either toss in a little ice or just don't use it for more than an hour or so), but other than that, I can scare imagine a more benign additive. (unless someone is allergic to milk).
