Description: This demonstrates the difference between hard polymers and soft polymers. The bag does not leak water as it molds to the softer polymer of the bag. If the pen had poked a harder polymer, most likely, there would have been leaking from the holes. This demonstrates characteristics of water, and how polymers can work. This also shows how certain leaks can be stopped.
