Super cool pop tubes.
They come in bright colors and make amazing sounds.
Simply pull both ends to make the tube expand then compress the tube to make a really neat sound almost like water filling the tube.
With supervision, you can even twirl them over your head to make a whistling sound. These sound tubes are really fun and would be great for audible stimulation. You can also connect the tubes to each to make shapes.

Colorful Play and Pop Tubing – A fun, interactive toy for kids, these pop tubes let children stretch, build, connect, spin, bend, and play with them in a variety of ways.
Create Unique Sounds – These stretch tubes also become sound tubes! Push or pull them to different lengths, lightly swing them in circles, and kids can create music.
Stimulating Creativity – The tactile feel of each tube is great for physical stimulation while the connectable, build-able design can be used to strengthen fine motor skills.
Home or Classroom Fun – Great for toddlers, preschool classrooms, and early learning occupational therapy kids of all ages will love bending and pulling each one.
