This was a fun experiment that resulted in some very colorful pasta that we used as a craft. You'll need pasta, rubbing alcohol, food coloring and some plastic bags. We also used some glasses to rest the plastic bags in while we were pouring. Add 1/2 cup of rubbing alcohol and desired food coloring to bags. Mix in pasta. Seal your bags and let them sit for an hour or two. Drain all the liquid and allow the pasta to dry overnight.
