This is considered to be one of the most toxic nuclear bombs to have been made. Detonating one Tasr Bomba, its results could be seen within a 100-mile radius. People within a 62 km radius suffered from third-degree burns and the air was unbreathable. 

It was made by the Soviets and detonated in 1961. Luckily for us, Tasr Bomba is not currently owned by anyone. Maybe there is a limit to chemical warfare and is not always about winning.

Sulfur Mustard

Gas Chamber is not necessarily a weapon, but it was weaponized to kill people. Gas Chambers were used in the Nazi extermination camps. The inmates of the camps were locked in a room with a small opening for the pipe to let in the engine exhaust. 

It is truly one of the cruelest ways anyone can think of to end someone’s life. About 50,000 Jews lost their lives in the Nazi concentration camp gas chambers alone, many more lost their lives to other horrors.

White Phosphorous

White phosphorous can give you second-degree burns and third-degree burns. It gets absorbed through your skin and affects your liver and kidneys. It is extremely painful and even the healing process takes a lot of time. 

White phosphorous starts igniting almost as soon as it is exposed to air. When it gets to your lungs, it turns into phosphoric acid. And the scariest part is that the fire it creates cannot be stopped by water.



Richard Fiedler invented the flamethrower in 1900. This invention has been deemed so inhumane that nations have had discussions on whether it should be legal or illegal to use. With a range of 60 to 150 feet, they can easily clear out bunkers in a single trigger. 

Once they are used, the flames cling to you until the fuel runs out. It is a horrifying creation that keeps both people in danger; the giver and the receiver. The person who is carrying the flamethrower becomes everybody’s target and the person on the receiving end is not the luckiest person.
