Cool it / Intelligent ball

Cool it
Cool it

"Cool it" is a spherical product that senses sound. Its outer casing is made of silicone. Under normal circumstances, the ball can be placed in the corner as a decoration. When a quarrel occurs, the ball can automatically scroll to the sound source by monitoring more than 70 decibels of sound, making it large and red, attracting attention. When people feel the ball, they can calm down and think about whether their behavior is normal by kicking it. If they continue to argue, it will continue to roll until the quarrel stops.
Let the quarrel cease to exist and give the child a good environment for growth.
