In this instructable (snicker) you will learn a very cheap (snicker) easy way to (hahahahahahahahahaha) prank your friends with just some glue and a water bottle.

Step 1: Take the Top Off (Duh)

Take the top off what more can i say in a screwing motion. :P

Step 2: The Glue

Okay I used non-toxic white glue but i suggest clear superglue for 3 reasons 1. It squirts out more slowly and will stay on the rim better 2. its clear 3. its stronger but if they get the top off stop them or it may not be such a harmless prank. So put glue around the rim.
