Inspired by Captain Underpants books, I made hypnorings for my sons, complete with color illustrations. Afterward, I listed a few extras on Etsy for sale at https://www.etsy.com/listing/109577605/glow-in-the-dark-hypnoring. Don't forget to use them wisely - hold the hypnorings in front of your elementary school principal and command obedience in Captain Underpants style!
