This shaken sensory toy makes a slight pop by pressing the mouse over the bubble and then it flips to start again. It won't sound like bubble wrap, but it's also a lot of fun. Fidget toys for kids are made of high-quality soft silicone gel, environmentally friendly and child-safe. Durable, washable, and comfortable to hold. The toy is very easy to play by taking turns popping the bubbles and pressing all the bubbles you want in a line. The player who presses the last bubble loses.
