MSU Question

Dear Atlas, I recently purchased a copy of Mad Scientist University for my birthday and so far it looks like a fun, creative game in much the same vain as "Once Upon A Time". Unfortunately, the rules were somewhat vague in places leaving me with a few questions:

  1. At the end of the turn, do players draw new Unstable Element cards?
  2. If yes to the above, do they keep their existing cards?
  3. If yes to the above, must their plan involve both Unstable Elements or can they choose one or the other?

Thankls in advance for your replies.
