Video: Hey, kids, let's have some fun in gas masks!

Students training for a mustard gas mishap in Pueblo.

There are some memories from elementary school that just seem to stick in your mind: The time Tanya broke her arm on the tire swing... the gym teacher singing "Wind Beneath My Wings" at the school talent show... all that hilarious farting.

But after watching the video after the jump, one can bet that elementary-school students in Pueblo will remember the time that weird lady from the goverment came to their classroom to talk about chemical weapons and made everybody try on gas masks. No, it wasn't for Cold War History Appreciation Month. Apparently, the U.S. Army is building a facility to destroy 2,600 tons of mustard agent stored at the Pueblo Chemical Depot and officials want to prepare the population for any possible, er, misadventures.

But there's no reason why preparing for a horrific, skin-melting accident can't be fun, right kids?
