OKay, so this question has been bugging me. I asked my friends and none of them knew, but anyway... you know those toy bottles for dolls that look like they have milk in them and when you turn them upside down, the milk goes away? What is the liquid inside them, really? Please help.
:D

Haha I've wondered this since I was little too!
