Have you done this? It was actually way easier then I would have thought.
Here is what you need:
Put noodles in a bag and add a few drops of food coloring to the bag. Then add about a tablespoon of the rubbing alcohol and the pasta.
Seal the bag and mix up tell all noodles are covered and you have the color you want. Let set a few hours.
I used cookie sheets with wax paper. Then put the noodles on top to dry. We let the pasta dry outside for a few hours.
This is a perfect craft because you can make a million more crafts with it 🙂
