Super Slow Motion Video of Firecrackers Exploding Underwater Filmed at 120,000 FPS

Dan Gruchy and Gavin Free from The Slow Mo Guys filmed firecrackers exploding underwater at 120,000 fps. The video is a revisited experiment that they tried previously but could not get the speeds they wanted to achieve until they could borrow a faster camera.

Gav and Dan usually blow stuff up in regular air, but did you know you can also blow stuff up in other places?
