Introduction: How to Put Water Into an Upside-down Cup!
This is a pretty simple trick that can be done with items you can find at home. The trick is an upside-down cup with water in it. If you pick up the cup, the water goes everywhere. This is actually my first instructable and I am submitting it to the april fools contest. Please view this!
Step 1: Stuff You Will Need:
This stuff you will most likely have at your house:
-a cup
-some water
-some ice
-a piece of THIN cardboard (you can cut one from a cereal box, and it will need to be bigger than the cup's lip
-some towels (optional, it is nice for clean up)
Step 2: Step One:
This part is easy.
Fill the cup with water half way and put in some ice.
Step 3: Step 2:
Put the piece of thin cardboard on top (make sure that there is a seal on the cardboard) and flip the cup over. If you have towels, place them around the place where you are going to put the cup.
Step 4: Step 3:
Remove the piece of cardboard before it gets to soggy. Remove it fast! You will have a little water leaking, but it is okay. Clean up and now you have you joke!
Step 5: More Ideas
Another thing you could do is do this a bunch of times on an entry way into a kitchen or some other flat surfaced location. The victim would be trapped then because they can't just pick all of them up. They would have to get a piece of cardboard and take out every single one out of the entry way.

That would not work.

It works a bit better if you fill it right-up, having air makes it a bit more prone to leaking.

Also, if it's filled all the way it just looks empty.
