Fun Facts
"The Hiroshima atomic bomb had a yield of approximately 15 kilotons of TNT."
"The largest nuclear weapon ever detonated, the Tsar Bomba, had a yield of 50 megatons."
"The energy of 1 kg of TNT is comparable to the energy in 1 kg of chocolate, but TNT releases it millions of times faster."
