Here’s the how to…
First, you begin with the main ingredient: CARBS. Err, I mean, pasta. I used linguine, but you can pretty much use whatever shape of pasta you’d like.
Cook it al dente according to the package instructions. But while it’s cooking, prepare your large Ziplock bags of food coloring.
I used six colors (red, orange, yellow, green, blue and purple), but you can use however many colors you prefer. Add about 20 drops of food coloring and 2 tablespoons water to each bag.
Then once the pasta is done, drain it and then immediately run cold water over it in a strainer or colander to halt the cooking.
Transfer the pasta, portioning it as you go, into the bags of food coloring. Then seal the bags, and mix the pasta and food coloring until well-combined. Let each bag sit for at least a minute.
Then one by one, return each bag to your strainer, give the pasta a second cold water rinse, and then transfer the pasta back into your pot. When all of the colors of pasta have returned, toss the pasta together until the colors are combined.
And then serve! You can top with your favorite sauce or toppings.
