About this effect
Five polished steel balls hung in a line from a chrome frame. Swing one in and one swings out at the far end; swing two and two leave. It keeps going far longer than seems fair, and nobody walks past a desk with one on it without touching it.
The classic executive desk toy, and a white elephant gift that people actually keep.
Questions
How does a Newton's cradle work?+
Lift one ball and let go: its momentum passes through the row and swings out the last ball. Two in means two out. Our desk toys guide explains why.
Is it a good office gift?+
It is the classic executive desk toy, and one of the safest gifts for a colleague you do not know well.
How long does shipping take?+
Orders ship from our supplier overseas, and we don't quote a delivery date because we would be guessing. Tracking is emailed as soon as your parcel is dispatched. If you need it by a particular day, order well ahead. Orders of $75 or more ship free.
