How to Burn a Candle Underwater
Here is a fun, quick experiment you can recreate at home with only a few materials: burn a candle underwater. The flame doesn't last long, but there is a glorious period of time where the candle continues to burn despite being submerged. On YouTube, DaveHax demystifies the magic: cold water keeps the outside walls of the candle solid, which in turn works like to a boat to protect the flame from being dampened. Of course, the water sneaks in eventually, but it's fun while it lasts.
