When I read about JDaniel4sMom's experiment of dyeing popcorn kernels, I remembered we had some in the cabinet and thought Kay would get a kick out of it.
We did ours a bit differently. I poured a bit of vegetable oil into a baggie, Kay added a scoop of popcorn kernels, and I dripped in some food coloring. For the next bag, we used less vegetable oil, and for the last bag we used none, just the kernels and the food coloring. This wasn't actually intended, I just realized I put way too much oil in the first bag, so we used less in the second, and then by the end I decided we would do this experiment-style, with Kay making guesses about which would come out the best colors. (I know I had no idea myself!)
We let them sit a few hours (this was the hardest part for my impatient little girl) and made observations about which kernels had held the color the best (green, no oil, was the winner there). Then we popped them up to see what would happen. The blue kernels (with the most vegetable oil) came out the lightest color, with the red (less oil) came out pretty good. But the green, with no vegetable oil on it, came out the best!
Afterwards, we ate our colored popcorn and watched Cinderella. All in a day's work!
