This was a really cool experiment I did this afternoon with the Eskimo. We had some leftover milk that I had forgotten to put away. It had been sitting out long enough that I didn't think we should drink it, but definitely hadn't gone bad yet. Perfect for an experiment! I poured the milk in a bowl and added a few drops of food coloring. Then I dipped a toothpick in dish soap. Dip the toothpick in the bowl of milk and boom! Exploding colors!
Seriously, this is so cool, you should try it right now. I don't care whether or not you have kids, this is worth doing. I'm sure there's a whole bunch of science-y stuff to explain it, but I am not a scientifically minded person. I hope y'all have fun with your very own bowl of fireworks!
