  • Bendy straw
  • Scissors

Instructions

  1. With the scissors make a small hole in the bottom of the cup (you might need a friend to help).
  2. Push the straw through the hole so the bendy bit is inside the cup
  3. Glue or use some Blu-Tack to seal the hole and hold the straw in place.

Results and Explanation

Once the water begins to flow through the straw, the rest of the water follows as it's pulled through.
