Paper Popper

Enrichment Activity for 5-11 11-14


What you need

  • An empty wine bottle
  • Piece of paper

Instructions

  1. Scrunch up a piece of paper small enough to fit into the neck of the bottle
  2. Hold the bottle horizontally and place the piece of paper just inside the neck of the bottle
  3. Try to blow the piece of paper into the bottle. The paper will fly out instead

Results and Explanation

The bottle is already full of air, so it's very hard to blow more air into it. When you do blow into the bottle the air comes back out, pushing the piece of paper out.
