(54) | Amusement device |
(57) An inflatable noise maker (10) has a substantially cylindrical hollow member (12),
made of a flexible, substantially non-stretchable material. The member (12) is sealable
at both ends (14) and houses a column of gas. The gas is at a pressure such that,
when the member (12) is transversely folded, the gas reaches a pressure above atmospheric
pressure, thereby tensioning both distal ends (14) of the folded member (12) such
that the distal ends (14) of the noise maker (19) vibrate at at least one audible
frequency when struck. |
