In this video, I got some butane and decided to fill up a dog bowl full of dish soap.. which allowed me to use the butane can in the soapy solution to make dense soapy butane bubbles, which easily lit on fire and caused a deflagration. Next time I will probably do way more butane bubbles for more explosive butane bubble fun! br Probably not wise to use a lighter to do this but I just wanted to see the butane bubbles on fire.
