Click-clack-rage

The click-clack craze where two plastic balls are tapped together with a string. At a factory in Woerden about 50,000 bundles of balls are cast every day. The balls are detached and attached to each other with a piece of string. Another craze is the crying tube, a hollow plastic tube that makes a howling sound when spun around quickly. Furthermore, a hammer that makes noise for small children.
