What do you think will happen if I stick all these pencils through this bag full of water? Will the bag pop?
- HOW DOES IT WORK?
The zipper-lock plastic bag is made out of a polymer called low-density polyethylene (LDPE). LDPE is used all over the world for packaging because it is low in cost, lightweight, durable, a barrier to moisture, and very flexible. The bag’s flexible property helps to form a temporary seal against the edge of the pencil so it can go through properly without breaking the bag.
- WHAT I LEARNED FROM THIS EXPERIMENT
The force needs to be (pencil) perpendicular to the surface (zip-lock bag). How to apply Pascal's principle and formula to my experiment. How force and area will equal to your pressure. Why pressure has to be equal everywhere to get accurate results.
