With my School Bus Wine Stopper
in the Yellow Strong & Flexible Plastic, I noticed the engraved details really popped when there was a light behind them. I'm taking advantage of that same property with my Cthulhu Jack-O-Lantern. The lid is a separate piece and a small LED light can be placed inside, such as the "Orange and Purple Submersible Light
" available at Party City.
Cthulhu's engraved head and tentacles light up. Meanwhile his eyes remain menacingly darker.
