Select your choice of tubular pasta. Any pasta you can string through will do. I used Rigatoni, Pennette, Tortiglioni and Ditalini.
Fill bowls half way with water. Put 10-20 drops of your choice of food coloring in each bowl and stir. (The natural color of pasta can even be used as one of the colors, in which case, be sure to set some aside).
Distribute pasta evenly into bowls. Shift them around so they are completely immersed. Let sit for 4-5 minutes.
