  Uranium, neutron initiator and plutonium is used for the atomic bomb. The uranium slides down a funnel when the bomb makes contact with the ground and hits the plutonium. The uranium and plutonium are exacaly like magnets but instead of sliding to each other they repel and ram out of the funnel into two different types of neutron initiator. When they connect they explode, sending toxic gases into the atmosphere as well as a big explosion. Sending a mushroom cloud in the air and getting people sick from the radiation fallout.
