Then we swirled the colors with a knife then poured the mix in the cups covering the colors.
We popped them in the oven, and made our predictions about what was going to happen to the colors once the cupcakes were done.
When they were done, she wasted no time testing her theory that the colors were going to be hidden in the cupcake.
"I was right, Mommy!!! There is the red!"
And of course she had to eat another one to make sure she could find the green :)
All in all, it was a success. For a more dramatic effect, you can add more food coloring and swirl it more. You can also put more than just one color per cupcake.
