Oxy-Acetylene Explosions at Ultra-High Speed

Finnish adventurers Lauri and Anni Vuohensilta (of the Hydraulic Press Channel and Beyond the Press) are obviously doing well with their YouTube videos, as their toys get more and more elaborate and expensive. So if they can afford this expensive camera setup, why is Anni wielding an acetylene torch duct-taped to a broom? It's the fame, not the fortune, that got them a Chronos ring of 72 cameras in order to make high-speed videos in a new series they call Bullet Time Show. They begin with blasting oxygen soap bubbles with an acetylene torch. Both Lauri and the guy behind the camera company explain more about them in the reddit thread. A good time was had by all.
