Wild colors in the name of science

Filed under: Activities: Babies

I stumbled across this video of a pretty nifty experiment that's easy to do, is dirt cheap -- you probably have most, if not all, of the ingredients already -- and will totally amaze and wow your kids. Yes, even your jaded teenagers. Simply fill a deep plate or shallow bowl with milk -- whole milk will work best, but any will do -- and add a few drops of various colors of food coloring. Then, with the kids watching, put a drop of dish soap in the middle. Stand back and let your kids tell you how cool you totally are.

Then, when they're all begging to know how it works, you can hit them with the chemistry lesson. Soap molecules are designed to latch on to molecules of fat, like the fat in milk. As the molecules move around connecting up, the food coloring gets tossed around willy-nilly, like a nerd at a crowded nightclub. Even if your kids don't get all the details of what's going on, you'll still get credit for being cool and, after all, isn't that what's really important?
