We made rainbow Pasta it is super easy. Just Boil the Pasta till al dente. If the directions say to cook for 12 minutes I usually cook for only 10min etc
As soon as you are done cooking the pasta run it under cold water. I get my hands in there and flip it around make sure the pasta is cold and has completely stopped cooking
Next separate pasta in baggies and coat in oil just enough to coat pasta NOT so much that the pasta is swimming in oil
Add food coloring or liquid watercolors
Let the kids enjoy! I threw some googly eyes in ours.
