The twist is that both glasses are filled up high and she poured it without the water overflowing. What may be the solution ( I am not so sure...) is that the bit in the cup where it grows out near the top, makes the water fill up less ( by which I mean it stores more water ) and so that makes it stay at the top. Another reason could be that part of the water in the second glass is fake. Therefore, if my reasons are wrong I will not be very surprised.
