There are thousands of videos out there showing how to make a potato cannon. But this clip from The Backyard Scientist shows how to use one to launch a glider. Working with his pal Joe – with a nod to the guys at FliteTest – they work out the most balanced and airworthy glider design.
THE BEST The Backyard Scientist
The Backyard Scientist continues to bring the danger with his latest build, an oversized weapon inspired by Maester Qyburn’s dragon-stopping Scorpion from Game of Thrones. This version is drawn with a motorized winch, and doesn’t seem nearly as powerful, but it still is deadly.
A while back, The Backyard Scientist built a massive mousetrap and used it to smash things. He decided to take all of the energy stored up in that giant spring and use it to drive an axle. Unfortunately, it seems as if its power should be measured in mousepower, not horsepower.
The Backyard Scientist can’t be bothered to cook the meals he got from Blue Apron using normal kitchen appliances. Instead, he turns to more dangerous methods, like a powerful arc flashlight, a high-voltage transformer, a blowtorch, and delicious manganese heptoxide.
The Backyard Scientist’s latest build is one of his most dangerous yet – a gun that fires a stream of searing hot molten pewter, or just about any other liquid. Needless to say it shouldn’t be fired at anything or anyone you care about – unless it’s filled with ketchup.
