A friend of mine has a big Halloween party every year and this years theme was glow in the dark. I made this skull cake with light up eyes and I used tonic water to make the icing that I used to pipe on the cake in the hopes that it would glow under the black lights. Unfortunately the icing didn’t glow that much, but the eyes looked really cool. The eyes were done with tiny battery operated LED lights that I covered in plastic wrap. Then I made very thin gumpaste eyeball covers for the lights. TFL!
