Review on BUNMO Pop Tubes Sensory Toy by Eric Jenkins

My daughter (and I!) definitely enjoyed putting the tubes together and pulling/pushing them to create different pitches depending on the overall length of the tube and certainly mesmerizes the hands holding the tube move up and down. Wrinkles as they stretch. Like other kids, my daughter got creative and thought she could make noise out of whistles by stepping on them. This caused some of the folds to lose their shape, rendering the pipe parts unusable. It seems irreversible. Supervised play is required - not for the safety of your children, but for the safety of toys.
