Sail Design Pendulum Newton Cradle Pool
Out of stock
Material: Plastic + Iron
Plunge one, two, three balls and see different effects
There are many ways to play, it depends on your imagination. The ball cannot be moved permanently. Only in a certain vacuum state will it move permanently. !! !!
Use one ball to push the other 4 balls, you will find that only 1 ball will swing back and forth; if it is 2 balls, 2 balls will swing naturally
Allows the ball to swing evenly without using electricity. It is a small craft that kills time when bored
I also found another function-hypnosis
Do you feel pain when you don't want to fall asleep? When you count sheep, do you feel that you are too naive?
Then please use this to see, pick it up on the table, move your eyeball as the iron ball collides, and it won't take long to guarantee that you will sleep peacefully!
