The science: Plastic bags are made out of a polymer called low density polyethylene (LDPE). A widely used packing material, and the tip of the pencil slips between the strands of the polymers and pushes them out of the way but sealing the area around the pencil.

Please keep the bag over the sink, or outside when removing the pencils.
