One of our New Year resolutions is to do more science projects. I think last year we might have done one or two. It's hard to get the materials that most experiments call for, so I'm constantly looking for super simple ones. Today we did the milk-foodcoloring-soap experiment. It's really more of an art project, but still good on the science front to explain the different densities of liquids and how they interact.
1. Pour some milk onto a plate
2. Place 2-3 drops of each color, close together, in the middle of the plate.
Don't worry if the drops sink into the milk.

3. Wet a Q-tip in dish soap.
4. Dip the Q-tip into the center of the drops.
Leave for 2-3 seconds and lift the Q-tip, and watch the colors swirl.

4. Now "paint" with the Q-tip. Put in some more drops.
Don't move too fast or the colors will mix into brown.

It was cool, and super easy.
That is really cool! We haven't done that because of a dairy allergy, but the colors and patterns are fantastic!
ReplyDeleteWe don't drink the stuff either, but dh does in his coffee, so milk is in the house. We're not that allergic to it, but it's always seemed kinda weird to me to drink another animal's milk.
ReplyDeleteIt wasn't until we discovered our dairy allergy that I started thinking about where milk actually comes from. Yeah, totally weird!
