Vase Candle
Plenty of protion of a candle has been wasted by melting.
This candle has a support like a vase at the bottom. The melted candle flows down on the vase, and then be solidified again. When melted candle piles up on the vase, it becomes an another reusable candle. Therefore, an user is able to use this recycled candle one more time.
