Few motifs of science fiction cinema have been more appealing to us than the subtle defiance of gravity offered by futuristic hovercraft. So every once in a while we check in to see how humanity is progressing on that front, and whether the promise of hoverboards will be delivered by 2015 as evidenced in Back to the Future Part 2 .

Australian inventor Chris Malloy has built a hoverbike from motorcycle parts and claims it can fly up to 173 mph, at an altitude of 10,000 feet.

But perhaps more interestingly, there are a ton of insane experiments scientists like to do with gallium.
