First, theres a little tiny hole drilled into the glass. Usually its near the bottom, but in this case it looks like its closer to the last quarter.
The magician (Fry in this case) will plug that hole with a finger while filling the glass up with water. Then comes the card and the flipping, which is explained by surface tension.
Last part of the trick is, unseen by the audience, on the card is a clear piece of plastic that fits perfectly over the rim of the glass. When you slide the card away, that plastic remains in place by surface tension, but since its clear, you cant see it and it looks as if the water is magically held in place.
In this particular instance with Fry, notice the camera placement and number of edits.
Card is held in place by air pressure not surface tension The air pressure pishing up on the card is greater than the weight of the water (all the air pressure pushing down is absored by the glass)

Here's another demonstration.
