I show how to make a secret compartment in the bottom of a candle. This project uses a regular candle that is modified by drilling out a compartment into the bottom. The compartment is then sealed with a plug that can either be made of foam, cardboard or melted into a disk from the wax that was removed. A sticker, candle label or circle of paper is then glued to the bottom of the candle covering the plug and hiding whatever is inside. This is a pretty simple project that can be done by using a drill and hole saw bit to save time but you can also carve out the inner compartment with a sharp knife. The candle will still work like normal just be careful not to let it burn all the way down as it will reveal whatever is hidden inside.
