One of the many challenges of colonising Mars is that the planet is lacking many of the natural resources we rely on here on Earth. We'll need to bring as much of what we need to survive as possible, but you can only pack so much into a spaceship. So scientists are developing ways to utilise at least one of the red planet's most abundant resources: Dust.

Like death and taxes, drone crashes are basically inevitable. Even experienced pilots aren't immune to hardware failures or software problems. But instead of building drones stronger, or wrapping them in awkward safety cages, Swiss researchers have designed a flexible quadcopter that squishes when it crashes, minimising the damage it takes.

Most high school students struggle to write a passable essay on Catcher in the Rye, but Blake Hawkins has more than earned his high school diploma — and some spending money on the side — by turning an unused locker into a fully-functional soft drink vending machine.

Video: Tall buildings often have tuned mass dampers hidden inside their structures to stabilise them against the wind. Those tuned mass dampers are huge and heavy and help limit a building's movement by swaying in the opposite direction of the building. That is, if the wind is making a skyscraper sway to the right, the damper will sway to the left to dissipate the kinetic energy, and reduce the, um, swaying. What's interesting is that the Burj Khalifa, the world's tallest building, doesn't have that.

Our perpetually-dropped smartphones have pushed glass manufacturers to create stronger and more durable materials to survive our clumsiness. But if you're curious just how advanced glass making techniques have gotten, someone has made a 9m working glass slide that's completely transparent.

Video: Forgotten Weapons sees a lot of odd firearms, from a machine gun that Italian troops would mount to bicycles to Uzis that look like horseshoes. But the Frankenau purse gun takes the cake for pure strangeness.
