Whoever came up with the paper cup is our friend. What a useful device! From one sheet of paper, you can make a cup that holds water.

 

Start with a square of white paper - unlined, with no ink that might leak. If you're using a common piece of 8½" x 11" typing paper, cut off 2½ " from one end to form a 8½" square.

 

Fold the square in half to form a triangle.

 

Fold the left side of the triangle in, and the right side of the triangle in. It will look like a mini envelope with the flap sticking straight up.

 

At the top, you'll have two triangles; fold them down on each side. Crease. Stick your fingers inside and work it apart into a rounded shape.

 

Voila! A cup! Open the top. Fill with water. Toast yourself! And drink.
