It is amazing how so much comes from so little - the splitting of atoms from uranium and plutonium can release an enormous amount of energy. Some people used this in making the Atomic Bomb which caused so much destruction and death to so many places and people.

1) What can you do to make the study of atoms benefit many people?

2) How would you prevent bad people from doing the same mistake again?
