The Slinky Pop Toob is an awesome stress reliever and a good science toy to show physical change. Stretch it out to make a popping noise. Bend it, stretch it out to over 4 times its size! (28 inches). Connect it to other Pop Toobs and make fun shapes, and spin it to make noise! It comes compressed at 7 inches long and makes a popping sound as you stretch it out and push it in. Get a bunch of Slinky Pop Toobs and link them together to make a giant snake or other shapes. Once you pick it up and play with it, you wont want to put it down!

Incredible Science Fun Learning Ideas:

Great item to demonstrate physical change
Provides tactile stimulation, fine motor skills and auditory feedback.
Learn about sound waves, frequencies, wavelengths and Hz in this fun, hands-on science experiment.
Learn about fluid dynamics and Bernouilli's principle. As you swing the Pop Toob, there is higher pressure in the part that you are holding versus the swinging loose end. The higher pressure sucks in the air which creates the various sounds you hear.
