Swing one or two spheres, and then loosen your grip, because of conservation momentum and energy the other one or two balls on the opposite side will move to the same distance! If you feel upset, swing two or three balls at the same time. It can make you calm ATTENTION: please take out the balls one by one please place the Newton's Cradle horizontally, and then the balls can move longer Package：1*Newton's Cradle

I am really disappointed in this Newton's cradle
I am really disappointed in this Newton's cradle. Like other reviews had stated, mine did not stay in motion longer than a second or two. If my husband hadn't already recycled the package, I'd return it. The base is really light weight and doesn't seem very durable for extended play or transport if you wanted to take it to school for a lesson. I had hoped to introduce Newton's first law to my young son this way, but it lost energy too quickly.

The wires on which the balls hang were constantly getting tangled. And the movement would stop after just a couple of swings - not at all how it's supposed to work. Returned.

Didn’t work more than five seconds, started to swing also which is bad for a Newton’s cradle, Amazon should be ashamed for selling this

It has a nice appearance and aesthetic appeal
The item came on time, packaged so that the string was not tangled. I expected the motion demonstrating Newton's law to last longer. It has a nice appearance and aesthetic appeal.
