You really cannot stop squeezing this ball. Soft and gooey, but not sticky. Looks like a round ball, doesn't it" Hold it with both hands, and turn it inside out to get a soft, spikey ball! Flip it back into a soft, round ball. Not only great for tactile sensation, but also good exercise for the hands. Hand function is enhanced since the movements require wrist extension and thumb stabilization as well as some isolated finger movements. The small ball is a great fidget toy as well.
