I was trying to think of what they were called earlier. My friend had one and would make snakes and bats. He was very popular when he would bring them into school and give them away. I also remember them having a rubbery chemical type of smell.
Remember when we rented VCR tapes? Had to wait for a movie to become available on tape. Never happened until after it finished in the theaters. Sometimes it was a year or so after it left theaters before it came out on tape. How bizarre.
