Have you ever been in a situation where you needed a drink of water either for thirst or for something like taking a pill? Here is a solution, learn this once and know it when you need it. There is a high probability, wherever you are, that there is a sheet of paper nearby. Notebook paper, a pamphlet, a flyeror printer paper. Anything will do. You can then fill it at the nearest faucet.

This design will use a standard rectangular sheet instead of a square one. Similar to this

Step 1: First Fold

The following steps will show you what to do, I used a two color paper to make it more clear. The step following the instruction will show that instruction completed.

First take your piece of paper and bring corners A and B together and fold.

Step 2: Fold 2

Now take corner A to corner B and fold.

Step 3: Flip

Now flip the whole thing over to the other side.

Step 4: Fold 3

Now take corner A to corner B and fold.

Step 5: Fold 4

Now take the half of the paper at A and fold to B. It is important that you fold both pieces at this point.

Step 6: Flip

Now flip the whole thing over to the other side.

Step 7: Fold 5

Repeat the same thing on this side, fold everything at A to B.

Step 8: Open Up

Now open up the center, you will have a pocket.

Step 9: Done!

Now you have a cup that will hold water for a few good minutes.
I used notebook paper and it soaked through almost immediately. I had no problems after I doubled up the paper though.
Nice pictures. Coincidently something related here:<br/><a href="https://www.instructables.com/id/SRB9CINF1A4XVGY/#C196H8UF1B3R7P4">https://www.instructables.com/id/SRB9CINF1A4XVGY/#C196H8UF1B3R7P4</a><br/>If you used plastic or waxed paper this would hold water for more than a few minutes?<br/><br/>L<br/>
or maybe painting the inner side of the paper with crayons ?
Yea, <em>colourful</em> waxed-paper.<br/><br/>L<br/>
Because of the design, it will hold 'till the water soaks through.
