The Newton Cradle Balance Balls will light up on the baseboard, and the glass balls will look colorful and beautiful, very attractive.

It demonstrates the third law of motion with swinging spheres; when one ball is lifted and released it sends force through the rest, pushing the end ball in the opposite direction

When you feel tired from studying and work, you can agitate the sphere to listen to the clanging sound to relieve it.

More information?  The equilibrium balls copy the "Newtonian Pendulum", the construction that formulated the third fundamental law of classical engineering, the so-called "action-reaction law". This law is captured in the most fun way on this Gadget. This play was invented in 1967 by English actor Simon Prebble and depicts Newton's theories about maintaining momentum and energy. If you want to play with Newton's pendulum, just raise one or more balls and then let them drop to collide with the others. The result will be different depending on how many balls you use each time. In any case, you will induce an endless rhythmic movement.

Why anxiety stone?

Our Mission Is Normalizing Mental Health

Started by psychologists, we want to see a world where conversations about mental health and anxiety are normalized.

The fact is, it's a process. And that one night of journaling, or making a candle, or doing aerial yoga can make a huge difference to how one feels.

At Anxiety Stone, you will find such tools, that may seem silly at first glance, but can have a profound effect when seen from the perspective of self-love.
