What you need


Plastic cup

Bendy straw


Glue or Blu-Tack



With the scissors make a small hole in the bottom of the cup (you might need a friend to help).

Push the straw through the hole so the bendy bit is inside the cup

Glue or use some Blu-Tack to seal the hole and hold the straw in place.

Slowly fill the cup with water. Once the water is past the top of the bend, water will start to flow through the straw.

Results & explanation


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