Along with annoyingly adhering to your TV screen and tabletops, dust can be a deadly material, exploding with enormously destructive force in places like coal mines, sugar refineries and grain silos. The explosive properties of normal dust are pretty well known, but what about non-traditional dust?
Why subject yourself to the dull buzz of fluorescent lights and endless data sets? Play with plastic explosives, dive with jellyfish, or make video games instead! These schools will make you wish class would never end.
Over the years, PopSci has pulled together annual lists of the coolest, funnest college labs, the places where we would like to have spent our youth tinkering, exploring, and learning. Here, we've collected the ultimate list of all the great labs we've ever covered.
U.S. Army Special Forces soldiers will deploy with the XM-25 weapon this summer, so that they can shower enemies hidden inside buildings with lethal smart rounds. Veterans of the Afghanistan conflict who tried the weapon predicted it would be a "game changing" gun capable of taking out insurgents hidden behind cover, Military.com reports.
The XM-25 resembles a highly sophisticated grenade launcher that fires laser-guided smart rounds. The laser gauges a distance to target and allows the warfighter to set where the round will detonate, adding or subtracting increments of 3 meters from the laser-spotted point. Then the scope tells a microchip inside the round how far it should travel before exploding.
It would be hard to describe a bullet as smart, but what if that bullet was laser-guided, radio-controlled, and carried an onboard targeting CPU? The US Army has announced the creation of the XM25 rifle, which can fire a new type of explosive round that fit that exact description. Imagine the implications: hitting targets inside buildings or hiding around walls. Whoa.
Not every student falls asleep at the thought of doing another lab. For a fortunate few, homework means setting off bombs, making lightning, crashing cars, and unleashing 100mph winds. Come meet the luckiest students in the country inside (with video)
