Yet another addition to a glowing pickle is trying to figure out what else glows.

My students were able to get a cherry tomato to glow. Though not as impressive as the pickle, it did work. I've always wanted to "marinate" a pickle in a different solution, such as potassium chloride with the hopes that you'd get a different color than the sodium yellow.
