What you need

  1. Water
  2. Clear plastic watertight bag ( e.g. watertight, resealable food bag)
  3. Some pencils





Instructions

  1. Fill the plastic bag with water
  2. Push a pencil through the bag
  3. Then another... and another

Results & explanation

The bag doesn't burst because the plastic stretches rather than tears as the pencils are pushed through it. If you take a pencil out you can plug the leak simply by putting it back through the holes.
