Gray Matter: The Hidden Uses of Everyday Explosives

When you stop and look, you may be surprised to find yourself surrounded by all kinds of explosives--some that detonate easier than dynamite

The explosive C4, a favorite for everything from demolition to terrorism to action movies, is in fact one of the safest explosives. How can an explosive be safe? If it’s hard to set off by accident. C4 is so stable that you can light it with a match (it burns but does not explode) or shoot it (it splatters but does not explode). To go bang, it requires a detonator that produces both heat and shock.

At the other end of the spectrum are mixtures that ignite simply from being scratched or knocked. There are obvious challenges in mixing, storing, and handling these substances so that they explode only when intended, yet they’re surprisingly common.

New Unmanned Chopper Sniffs Out Improvised Explosives While Looking Adorable

The Pentagon is testing an unmanned helicopter that can detect electromagnetic emissions from IEDs. Codename: HELIPANDA (we wish)

Roadside bombs have long represented the greatest killer of soldiers in Iraq and Afghanistan, but there's hope beyond the sturdy little demolition bots that already work with their human handlers. The Pentagon now has two aerial drones on the testing docket as possible countermeasures for improvised explosive devices (IEDs)--one of which we're calling 'Helipanda' for the remainder of this post.

New Explosives Test Could End Liquid Carry-On Ban


In 2006, a bunch of terrorists went ahead and ruined air travel for the rest of us. After the terrorists failed to bring liquid explosives onto a British flight, the airlines banned liquid carry-on items larger than 3.4 ounces. This forced us to leave shampoo at home and buy outrageously overpriced drinks by the gate, to say nothing of the flask of whiskey I liked to travel with.

Do You Have a Bomb-Defusing Ray Gun to Spare? The Navy Would Like a Word

Despite years of failure, the Navy continues to look for futuristic solutions to the IED problem

The U.S. Navy is still looking for an energy ray to defeat IEDs. However, unlike previous attempts, the new technology they're dreaming of would render the explosives inert, rather than prematurely detonate them.

Improvised Explosive Devices (IEDs), also often referred to as roadside bombs, have been the deadliest weapon used by anti-U.S. forces in both Iraq and Afghanistan. The devices prey on the U.S. military's dependence on roads for logistics; they target supply convoys and patrols alike. Unfortunately, many of these mines can't distinguish between U.S. Marines in a Humvee and an Iraqi or Afghan family in an Opel, leading to many civilian deaths as well.

Explosion Video of the Week: TATP

Why you can't bring liquids through airport security

Turn up your sound and chemist Gerard Harbison will explain it all. The tiny white thing sitting in front of the orange water balloon contains a mere 1/60th of an ounce of triacetone triperoxide (TATP), the chosen detonator of would-be shoe bomber Richard Reid. (Note: TATP is still explosive when it's wet, so it's probably one of the reasons for the TSA's draconian rules about liquids.)

Add a 9-volt battery and KABOOM.

But there's good news.

Ecologically Sound Explosives

Researchers are developing eco-friendly ways to blow stuff up

Who would think to make explosives more eco-friendly? After all, if enough explosives are used, one may argue, there won't be any environment left to be friendly to. But a team of scientists in California are trying to keep the environment safe even while producing a material that helps blow it up.
