Let's Make Some Hydrogen Gas!

Making explosive gas is a basic skill, and doing it can teach you a lot about chemistry. What you use that gas for is up to you. But please be careful. » 6/16/14 9:23am 6/16/14 9:23am

Best $20 Special Effect Ever: Make Metal That Tears Like Paper

Want to make everyone think you have super strength? Or maybe you want to do a short film where it looks like the fabric of reality is breaking down? All you need is some aluminum, some gallium, and some patience. » 6/11/14 1:30pm 6/11/14 1:30pm

This Fire Retardant Bursts Into Flame When it Touches Aluminum

Touch this chemical to aluminum foil, and it bursts into flame. That makes for a pretty fire (although it's a pretty dangerous one), but the chemical is a fire retardant. Find out why bromine goes pyro the minute it touches aluminum foil. » 5/13/14 6:40am 5/13/14 6:40am

This fizzy reaction could run your car -- or make it explode

A little aluminum, a little lye, a little water, and quite a bit of fizz. That bubbling looks sedate, but it's blown up a couple of trucks. And someday, who knows? It might be powering cars. » 2/17/14 10:46am 2/17/14 10:46am

The collision that created Earth's Moon is reenacted around an alien…

NLTT 43806 is a white dwarf, the dying remnants of a star like our own. But there's a problem. Its composition doesn't make any sense...unless there was a cataclysm just like the one Earth experienced four billion years ago. » 8/14/11 9:30am 8/14/11 9:30am

The next atomic clocks could keep accurate time for the entire life of…

The atomic clocks we've already got are marvels of precision timekeeping, but their successors could be something else altogether, losing less than a second every 80 billion years. That could allow us to probe some of physics's most fundamental questions. » 5/15/11 3:45pm 5/15/11 3:45pm

Japanese Aluminum House Radiates Heat

A Japanese architecture firm is in the process of creating the first house under its environmentally-conscious Aluminum Project, which will use aluminum walls both to save resources and to provide thermal radiation. Since aluminum is strong but light and easy to manufacture into flexible sections, it's highly… » 2/07/08 8:20am 2/07/08 8:20am
