If Star Trek has taught us anything, it’s that beaming things up is totally awesome. I wouldn’t mind beaming over another cup of coffee as I sit here right now, and that’s just for starters. Small strides have been made in the creation of real tractor beams (we’re talking microscopic). But here’s a new and interesting twist on this futuristic bit of technology: create it with water.
This is another one of those discoveries that shouldn’t work and has baffled, albeit happily, the scientists working on it. Professors Michael Shats and Horst Punzmann of the Australian National University figured out that wave generators, which you may have seen in swimming pools and smaller wave pools, can move objects floating in the water. But here’s where it gets weird: wave pools can move those objects against the waves.
