FALONG Science Balance Balls - Newton's Cradle Pendulum for Demonstrating Laws of Physics - Office Desk and Table Decor

Good product

The media could not be loaded. I like the product overall, the size is as expected and the oscillations last long enough for observations but i feel the quality is a little low. The pendulum is good but could have been better

This is broken within minutes, not having durability for the cost.

I was very skeptical about the packing of such a product. However I was pleasantly surprised in the nice manner in which such a delicate object was packed.

Quality of plastic was good but i didn't find this product worth buying bz balls movement is less then a minute and each time i keep on moving balls thats not possible. As a decorative items I thought the movement of ball in this might be continuous but actually I wasn't, so returned.

Frame Material is plastic, but it works and cheaper than the rest.

fantabulous

Does what it suppose to do but if strings get complicately entangled then it's pain to seperate it. Other wise good product.
