This sensory fidget toy helps you take out your stress by popping the bubbles! It is calming and relaxing and can be used anywhere and anytime, ideal for those with anxiety, autism, ADHD or sensory difficulties. One side makes a satisfying pop, the other is quieter for multi-purpose use. To use as an intelligent board game, two players take it in turns to push down any number of bubbles on a single row. The player who presses the last bubble loses!
