ABSTRACT:
A security device for attachment to a child by a support, such as a wristband, having a housing mounted thereon. The housing includes a first chamber and a second chamber sealed from one another until the device is armed. The first chamber stores an inert pressurized gas, such as carbon dioxide, and the second chamber stores a harmless, sprayable powder. An arming member is mounted substantially adjacent the first chamber for unsealing the first chamber to allow the gas to travel through the passageway into the second chamber. An activation member is attached to the housing for spraying the mixed powder and gas therefrom. Preferably, the device includes a clock having an exterior time display mounted to the housing.
