A holiday candy jar with light and sound effects having a signal sensor (10) which gets continuous signal from a signal source (12). When someone puts his/her hand into the jar trying to get a candy, the signal between the signal source and the signal sensor will be blocked. A control circuit board (20) is connected to the signal sensor (10) through wires (16). When signal is blocked, the control circuit board controls color lights (14) blinking and a speaker (20) producing a special sound for holidays.
