1 - Egg Candles These candles are made to look like a boiled egg sitting in a glass container. As the candle burns down, the ‘shell’ melts away, and the wax that dribbles out is coloured yellow to resemble yolk.
DIY Water & Oil Candle - uses floating candle wicks. Just add water & pebbles, float a layer of cooking oil and add floating wick. The site sells these wicks, but you can find them at Hobby Lobby and other craft stores as well.
