Mustard Gas was a poisonous airborne chemical compound used heavily throughout the world wars. Causing heavy blistering on the skin and even worse in the lungs, it was a powerful tool used by both sides to irritate, incapacitate, or even kill groups of enemy soldiers. It's also made by combining bleach with ammonia, which one innocent woman did while trying to clean her pool.

"This is why they tell you to NEVER mix chemicals!" @BigHern8885 commented. 

Fortunately, the woman's dog knew what was up immediately and left before things got bad. The woman however, decided to move the mixture closer to the pool, where it proceeded to explode. 

"She just made a deadly chlorine bomb. The dog knew what was up," @WEFkilz added.

But while the woman was lucky to escape her self inflicted gassing, plenty of viewers couldn't help but make a few jokes.

"Let her cook," @Phil_Official3 said, while others shared Breaking Bad memes. 

This is one formula that even Walter White would have shied away from.
