Fireworks are meant to be viewed on dry land, which explains why the underwater detonation of an M1000 in the video above amounts to nothing more than a pathetic pop. At least that’s what it looks like in real time. The Slow Mo Guys decided to up the entertainment factor significantly by filming the 0.01004-second process at 120,000 frames per second. The result is an explosion that expands into a glittering ball of light before imploding like a dying star. It should go without saying that setting off explosives in a fish tank shouldn't be tried at home—Dan and Gavin have plenty of experience handling dangerous situations.
