Tie-dye cupcakes... why not?

My 5-year-old decided he wanted a glow party for his birthday...  so we quickly became the house of all things fluorescent, colorful, and/or neon.  In our attempt to stay vibrant, I discovered DIY tie-dye cupcakes, described below:

1. Make a batch of white cake batter (I used Aldi brand cake mix- do what works for you)
2. Separate into 6 bowls and add food color drops as follows
1. Red: 12-15 drops red food coloring
2. Orange: 5 drops yellow + 2 drops red
3. Yellow: 7-10 drops yellow
4. Green: 7-10 drops green OR 9 drops yellow + 2 drops blue
5. Blue: 12-15 drops blue
6. Purple: 7 drops red + 2 blue
3. Line cupcake pans with tins and drop batter in by spoonfuls...  I did red first, then orange, etc.  Have fun with this- it is not a science, it's an art form! 
4. Bake according to recipe directions
5. Frost with fun colors
6. Warn guests with dye allergies ;)
