This EMP Cannon Stops Cars Almost Instantly

We’ve heard of electromagnetic pulses cutting steel in milliseconds, but apparently they can also be used to stop moving cars just as fast. The cannon demonstrated in the video here is still a prototype, but it definitely seems to work. https://gizmodo.com/electromagnetic-pulses-cut-through-steel-in-millisecond-5417441 The idea is that an electromagnetic pulse would be used to disable a car’s…

Jules Verne Was (Almost) Right

If John Hunter—a former physicist at Lawrence Livermore National Laboratory—is successful, the International Space Station may start receiving their supplies from a cannon. No, it’s no joke. First postulated by Jules Verne in his novel From the Earth to the Moon, the idea of space cannons is not new. Many engineers have toyed with the…

This Pneumatic Gun Can Put a Ping Pong Ball Through a Sheet of Plywood

Tennis Ball Cannon is a Dog’s Best Robotic Friend

Now, a beer launching fridge I can understand, but a tennis ball cannon? I find it amusing when someone spends a tremendous amount of time and effort building something that can automate basic functions—like throwing a tennis ball to a wiener dog. But the results speak for themselves. It is an inspiration for lazy people…

Gasoline-Powered 25-inch Desk Cannon Shows Your Cube Mates Who’s Boss

USB Missiles are fun (I shot Dvorak in the chest with one once, it did not induce a heart attack as I had hoped), but actual cannons are even more fun. This 25-inch field cannon is the closest you’ll get to having a Civil War cannon in your office—unless you’re the undersecretary of Civil War…

Ping Pong Ball Fired From Cannon Destroys Can, Self

In these shots, a ping-pong ball fired at an unnamed “near-sonic” speed destroys a metal can that, you’ll note, is first dented just by the cushion of air coming from the barrel. Kinda makes you wonder how much devastation the cannon could have gotten done without any projectile at all. If this rings of deja-vu,…

Leave it to the geniuses at the NIT Physics Lab in Japan to build a cannon that fires ping-pong tennis balls at near-sonic 700 Km/h, annihilating cabbages, Coke bottles and what look like sundry colorfully packaged snack-food items. There’s no dramatic tension here, just the satisfaction of seeing the strong overpower the weak. Want more?…
