Bagged water experiment

 The point of the project is to poke a pencil through both sides of a bag of water without the water leaking out of the bag.

Steps I followed get some sharp pencils, fill a plastic bag up with water seal the bag and then get your pencils and carefully stick them through the bag.

Discussion The zip-lock bag used was most likely made out of a polymer called low-density polyethylene (LDPE). It’s one of the most widely used packaging materials in the world. LDPE is low in cost, lightweight, durable, a barrier to moisture, and very flexible. The tip of the sharpened pencil can easily slip between. The material that the bag is made out of helps to form a temporary seal against the edge of the pencil. When the pencil is removed, the hole in the plastic bag remains because the polyethylene molecules were pushed aside permanently and the water leaks out.

Conclusion- Did it work? yes this worked a little bit. When I stuck the pencils through a little bit of water dripped out. If I where to do this again next time I would use more pencils.
