This Prank Can be done anywhere with little preparation. Befuttle friends and co-workers with this trick that only requires a plastic grocery bag and a mug or cup.In this trick you will be flipping a friend or co-workers cup,Leaving it upside-down and full of whatever was filling it before. I hope that you enjoy this trick and get some good laughs from it too.

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.
Have you tried doing it on a marble table or on a kitchen counter with someone's coffee or beverage it will get all over the floor and take even longer to clean up.
Love it!<br />
<p>You can do this if you get a bad waitress. First you put her &quot;tip&quot; in a glass and fill until you get the bubble over the top. Than cover it with a menu, there's always one on the table. Flip the glass, slide out the menu, than leave. When the waitress comes over she sees the tip under the glass and splash.</p>
wax paper is best,you got this fro the pocket guide to mischief?<br />
&nbsp;I did not think of that I will add it. No I didn't get it from that book, But I will definately look it up.
cool
I hope you enjoy it. I've definately had a good time with it.
It's important to make sure the cup is completely full isn't it? L
Not necessarily, If you flip it slowly with the bag pulled tight it works just the same. That would also be challenging to find someone with a cup filled right to the brim.
On that surface, there's only surface tension holding the water-in (which isn't in there is it?). It does work, but having a large amount of air in the cup makes it leak more. L
Yes, I guess you are right the more I had in the less it leaked. I tryed to take a picture with a clear cup but you could just barely see the water so I didn't include it. I will add that in. Thanks for your feedback.
There's jut a little bit of air in this one, which got in when I was pulling the plastic, but it works. L
