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