The Awesome VORTEX CANNON!

If you’ve been sitting around all week wondering how you could combine smoke, speakers, and a love of novel physics experiments into an excuse to tinker in your workshop this weekend, building a smoke-shooting vortex cannon should cover everything nicely.

Over at Make, the DIY-centric magazine, they’ve put together a video tutorial on how to build your own vortex cannons. The first cannon is essentially a super size version of the DIY Airzooka  just bigger is better! The second model they create, however, is powered not by an elastic membrane stretched across the back of the tube, but by the kick of a big speaker.

Instead of drawing power from the floor or ceiling like regular flat rides, these bumper cars seen around the San Diego area not only run independently – you can drive them down public roads.

That’s right, these bumper cars, which have been reconfigured to run on four wheels, are completely street legal. Even if they’re not, though, I doubt cops will pull you over for a ticket – they’ll probably ask to try it for a spin around the block, instead.

Clearly 007 had to be watching in the background

Designed by a team at Cranfield University in Bedfordshire this ultimate boy toy can climb a 407mm vertical wall, go down a 40 per cent side slope and operate in up to 610mm of water. You can use it to drive over obstacles, cross rivers and do all the things you wouldn’t want to do while in the car yourself. (Video)
