Pushing a Pencil through a Freezer Bag full of Water

In this video, Paul attempts to push a sharpened pencil through a freezer bag, or Ziploc, full of water. He also uses this simple science experiment to help demonstrate different English tenses to his students.
Watch, and find out if he manages to push the pencil all the way through the polythene bag without springing a leak! Things could get rather wet....

If you'd like to try this at home, all you need is a sharpened pencil, a freezer bag and water.....Oh! And your mother's permission!

This was originally used to get the students talking in one of our Junior High School classes (Paul will do almost anthing to get his students to talk!)
