5 Large Beads Newton's Cradle Balance Balls Desk Toys Office Decorations with Black Wooden Base Desk Balance Balls Fun Science Physics Toys for Office/Bedroom/Living Room

I created a basket for apartment Manager, she loved it.

This is a fun item to have at home or work desk. Rarely can anyone pass it without playing with it. My husband took it to work but didn’t use all the original packaging and it fell off car seat to a tangled mess. Good thing I do those tangled puzzle strings on my phone since I was miraculously able to untangle it. Lol

Person receiving it really liked it

Movement is very smooth and precise, no need to build,it comes ready right out the box,great gift,keeps you entertained for hours,functions very well showing the laws of physics and inertia,very durable.

Always wanted 1 of these finally have 1!!! Thank u this is awesome!!! Perfect size for desk...works fine...seems durable...great value for the money!!

The media could not be loaded. I wonder if there are any ideas for adjusting the intervals of sounds, like a metronome...

It doesn't work as long as it should. It's weights are all off. Cheap materials. It's more an example of chinese factory products than an example of physics.Though it does work. 3 Stars. Make Better Things.

Arrived in perfect condition and it is just what I was looking for.
