TransCup by David Ethan - Book

You drink your favorite soda in a cup, and at will, the straw goes through the cup.

From the book's introduction:
 
The idea of this trick came to me in a fast food restaurant: I finished my soft drink by playing with my paper cup and I wondered what kind of trick I could do with it...
 
Tapping on my straw while I was thinking about it gave me the idea: the straw through the paper cup!!!
 
Conditions for this miracle:

Be able to drink in the paper cup.
Be able to show the inside of the paper cup at the beginning of the routine.
Have no visible hole at the bottom of the paper cup at the beginning and at the end of the routine.
Use a regular straw without straw substitution.
Be able to make it easily, quickly (less than 30min) for cheap...
Easy to perform.
