Catapult your desk decor to new heights with this DIY project. Gizmodo recently shared a video by YouTuber Mist8k that gives a step-by-step tutorial on how to make a miniature catapult. The simple design is an adaptation of the leaf spring system invented by Leonardo da Vinci in the 15th century.
The easy-to-follow project involves measuring, cutting, and drilling as well as supplies like reused plastic and wood, bolts, nuts, acrylic, a cog from a toy, a spring, and some string. While the design of the entire model is important, Mist8k explains in the video above that the way the strings and launching arm are connected to the mechanism is key, because it determines how the projectile will fly: "You can see how I've attached the string to the shaft in such a way that when I pull the launching arm, the flexible arms tighten up and create torque."
Watch the video above, grab the necessary materials, and get busy making this cool little toy for yourself or someone who appreciates 15th-century engineering.
