Abstract
A amusement device for transmitting secret messages includes a central, generally flat, elongated core member for receiving the imprinting of messages thereon. A pressure sensitive sheet-like transfer element is wrapped around or placed adjacent a portion of the core material. The transfer element is coated on the side adjacent the core member with a substance which will transfer to the core upon pressure being applied to the outer side. The amusement device further includes an inner and outer wrapper, wrapped around the core member and pressure sensitive transfer element to disguise the nature of the device. A message may be written on the core material by using a stylus or other non-marking item to apply pressure to the outside wrapper. The pressure sensitive transfer element will imprint the message onto the core material such that when the core member is unwrapped, the message may be read. In one embodiment of the amusement element, the core member is a stick of chewing gum and the transfer element is coated with an edible substance.
