hackaday hacks a prop portal gun to actually levitate a companion cube. http://wp.me/pk3lN-mPR I was out to lunch with a couple friends, brainstorming ideas for fun projects when one of them says "Wouldn't it be cool if we could build a working gravity gun?". We all immediately concurred that while it would in fact be cool, it is also a silly proposition. However, only a few seconds later, I realized we could do a display piece that emulated this concept very easily. Floating magnetic globes have been around for quite some time.I determined I would tear the guts out of a stock floating globe and mount it on a portal gun, since they're easier to find than a gravity gun. I would also build a custom companion cube to be the correct size and weight necessary.
