But if the Candle burns for too long it can expand the cup enough to break the glass

@rhinohelmes Not to make your science teacher look bad, but that's not accurate. CO2 is more dense than oxygen by weight, but not by moles (the 'mole' unit is related to the actual number of molecules). A mole of CO2 does weigh more than a mole of O2, but takes up just about the same amount of space.

No the water is not being sucked up because there is no such thing as suction

@rhinohelmes Actually it happens because the air is, at first, very hot because of the flame. When the flame goes out from lack of oxygen, the air cools down, taking up less space and forcing the water to move and take up the extra space.
