- Balance Balls are a classic desk toy. Also known as Newton\'s Cradle, the clacking of the steel balls will keep you entertained throughout the day. Pull back one or more of the balls, release them and the same number of balls will swing up on the opposite side. This set of balance balls is fun for the office and makes a great desktop gift. The apparatus usually consists of an odd number of identical steel balls each suspended by a bifilar suspension from a sturdy frame.

Balls are excellent, they came quickly, and not to the post office and to the Post Office, for which special thanks!
Delivery to the Novosibirsk region is exactly 3 weeks (in a combined parcel with other orders). Tracking the parcel was throughout the way. The pendulum corresponds to the size in the description, but it turned out with a small marriage: the last ball is slightly out of a number of other balls and therefore the pendulduldul In general, the thing really liked children, for general development will go. I did not have to communicate with the seller.
