Looking for an easy sensory bin idea that you can prep in advance? These rainbow dyed corn kernels are low-mess, super colorful, and lots of fun to play with. Dye them once and reuse them again and again!
Mix 20-25 drops of food coloring into a small bowl containing 1 tablespoon of vinegar.
Pour the colored vinegar into the bag of corn.
Seal the bag and shake the corn kernels around until the food coloring has been evenly spread throughout. If the color isn't vibrant enough, add a few more drops of food coloring (but keep in mind that it the color won't look super vibrant until it has fully set).
Repeat the previous steps for every color of the rainbow.
Spread the sealed sandwich bags out on a flat surface and let the dye set for a couple hours, occasionally turning over the bags to fully coat the corn kernels with vinegar.
Pour the colored corn kernels onto a baking sheet to dry, making sure that the different colors don't touch each other. Once dry, the kernels are ready to play with!
