Rules:
 The class will be split into 4-5 teams.
 Each team will get one chance to answer a question.
 If the team gets the question correct they may choose
one person from any other team to join them. This
person must then help the new team to answer future
questions.
 If the team gets the question wrong, it is passed on to
the next team until it is answered correctly.
