Model Rocket Launch Underwater
Warped Perception regularly films super slow motion clips of random things in 4K, and his latest shows what happens when you launch a model rocket from underwater. In previous experiments, he fired rocket engines underwater and under liquid nitrogen, so it was assumed this would work. However, he really wasn’t sure how the rocket would break away from the water’s surface.



On a related note, did you know that during the early 13th century, the Chinese turned black-powder–propelled objects, formerly only used for entertainment, into weapons of war? These ‘arrows of fire’ were fired from a faux catapult launcher, and the black powder was packed in a closed tube that had a hole in one end for escaping hot gases, while a long stick acted as an elementary stability as well as guidance system. In other words, this was the earliest known form of model rocketry.
