Note, Wax paper works too, Quite nicely indeed. Thank you Ripstikfan.

Step 2: Pre-Flip.

Now that you have found what you will be using to flip the cup you will need to find a unsuspecting friend or co-worker to pull the prank on.Be sure that this person has a sense of humour and a desk that isnt an antique wood as a humourless person might freak about the water rings on there fancy desk and that isnt a good time for anybody.

This Trick works Best if the friend has a mug or cup that cant be seen through. It still works with a clear cup as it will still leave them wondering how to get it off there table without spilling all over themselves which is equally amusing to watch.

Fill your cup with water and pull the Grocery bag( or what your using in place of it) over the opening in the cup and pull it taunt so that there is no holes or spaces where water could get through.

Note. A cup with more water well have less of a tendency to leak. The less the water the more air pushing the water out. Enjoy.

Step 3: The Flip!

Well holding the bag taunt flip the cup 180 so that the opening is on the surface. You have now completed the flip.

Step 4: After the Flip.

After flipping the cup and placing it on the surface spread the bag flat. Hold the cup down and slide it across the flattened bag. Once the cup is off the bag wipe the excess liquid from around the cup and there you are its finished. Now go into stealth mode and watch your victim be absolutely kerfuffled.

Apologies for the Shotty camera work.
