Underwater Fireworks: How to Light Sparklers Submerged in Liquid
In this video tutorial, you will learn how to use sparklers, or fireworks underwater. You'll need some sparklers, tape, glass container, a lighter, and, of course—water.
Take a few sparklers and tape them up nicely without leaving any gap between the tapes. Leave a little bit of the sparklers exposed at the tip so that they can be lit. Now light the sparklers with the lighter and put them inside the glass container filled with water. They will burn under water right till the end. Sparklers contain oxidizers, which provide oxygen and allow them to burn underwater.
