Watch this crazy video of kids testing gas masks for the government in the 1960s

During World War II, the U.S. and Russia fought together as allies against Hitler and his massive German army. That "friendship," however, quickly soured after the elimination of their common enemy. The relationship was fraught with trust issues.

The U.S. started to get nervous, thinking the Soviet Union would one-day attack American soil with chemical weapons. So, to prepare for that awful possibility, the government needed to test gas masks (even on children) to ensure safety from chemical agents. To do so, the United States Chemical Corps developed a mask strictly for civilian use that looks like something out of Star Wars.

It's easy to look back at the U.S. and see paranoia, but this video suggests that the U.S.S.R. did, in fact, have a stockpile of chemical weapons.

The masks' manufacturers put filter pads inside to screen out radioactive dust and particles. In theory, the idea was sound but, like anything, the apparatus needed some practical testing.

The kids who would take part in the tests were fitted via with masks after a series of measurements of their faces were taken. Once each test subject — *cough* I mean child — was equipped with a masks, government workers escorted them into a chamber. The door was sealed behind them.

Then, the testing chamber was filled with a "fine" aerosol spray as the children read books and fun magazines to stay occupied. During the 10-minute period of exposure, the small room was filled with a large quantity of organisms.

After the test ended, the children were led out of the sealed room and the experiment was deemed a success.

So, that's cool.

According to the video, the masks were expected to "cost no more than several dollars." We bet the taxpayers were happy to hear that!
