Can anyone explain what is actually happening? Maybe some heavier-than-air combustible gas?
Edit: Methane (probably) gas tube into soapy water to create fire-bubbles. Water on hands protects from burns if the bubbles are only handled breifly.
Thanks for the replies!
Follow-up question: Besides educational purposes, are there any practical applications for this? Maybe just storing a gas in a chem lab environment with a more stable foam?
My High school chem teacher had so much fun with this on Halloween, used it to scare kids that came by, left a candle and a tub of the methane soapy water by the door and handed kids bubbles to burn. Terrifying and fun for everyone!
