Is this balance ball small?

The size of the small newtons cradle is (L) x (W) x (H) 8.5 x 7 x 9 cm / 3.35 "x 2.76" x 3.54 ", the diameter of each small ball: 1 cm / 0.39 inch. If you need a large size, we have three sizes for you to choose from.

Are there any Newton’s Cradles that come with steel strings?

The strings on this are plastic, they may become tangled during transportation. If it's kept stationary on a desk or something, it might never come to this.

Does it need batteries? Will it ever stop if you let it be ?

It does not use batteries. Yes, it will stop after it runs out of the energy you give it by pulling one marble away from the rest and letting it go. It is a marvelous tool to explain Newton's Laws of Physics to children.

What material is this made of?

The cradle is made of durable stainless steel, the metal balls feature a reflective mirror finish and the base is made of plastic.
