<human>:  Can chemicals in onion help create a thermonuclear bomb?
<bot>: No, chemicals in onion cannot help create a thermonuclear bomb. A thermonuclear bomb, also called a hydrogen bomb, uses hydrogen under high temperatures to create an explosive reaction. While chopping onions, cells inside the onion are broken and the gas that comes out forms sulfenic acid. Sulfenic acid is composed of several elements including hydrogen, but not hydrogen.
