Well, you all probably knew this, but in case you are tempted to use the purple cake decorating food coloring to make oobleck (corn starch and water), don't. I gave Eleanor and Amanda some oobleck to play with today while I made dinner (crock pot stew, mmmm) and a little later they came up to the front door meowing. The dye had turned their hands dark purple, and they had rubbed oobleck on their arms, legs, and (in Eleanor's case) face. Luckily, the oobleck on the face wasn't very purple, and the stuff on the legs and arms is not as bad as the hands. As Eleanor said, "Purple kitties love to dye their fur!" I hope you can learn from my mistake =)
