This is a simple life hack, but if you are desperate you can use a crayon as a candle. I personally have tested this out and it does work.
However, two things to know are:
- It takes a while for a crayon to start burning (about a minute). I think the paper on the crayon helps so cutting the top of the crayon off might make the process faster.
- The crayons do not burn long. In my test the crayon burned out in 10 minutes and when I tried again it burned out in 15 minutes
