This is a class project we did to learn about the plasma membrane and its parts. The phospholipids were made of a balloon, two straws and masking tape to hold the tails onto the balloon. They were tied together on fishing string, glued together with rubber cement, then hung from the ceiling. The other parts were cut from heavy paper.
