CRAZY FIRE BUBBLES (Smosh Lab) is a Smosh 2nd channel video in which Nick and Shayne create methane bubbles. The science behind this is that when the hand is dipped in water, the body is safe from any fire caused by methane gas, causing a safe flare of fire.
The video has been age-restricted.
"Time for another crazy experiment - this time, FIRE BUBBLES! Look out!"
