Abstract: A vibrating device is provided that comprises body with a first chamber having a housing therein and a bottom open end and a base securable to the bottom open end. The vibrating device further comprises a serial electrical circuit that comprises a battery; an electric motor secured to the housing, the motor provided with a rotatable shaft having an eccentric weight mounted thereon; a bulb having walls made of low electric conductivity material; a first and a second electrical bulb wire, each extending through the walls with an end extending into the bulb, and at least one bead made of high electric conductivity material provided in the bulb. The bulb is configured so that when the device is tilted beyond a predetermined angle, the bead comes into simultaneous contact with the bulb wires, so that the motor and the battery are electrically engaged allowing the device to vibrate, and when the device is below the predetermined angle, the device does not vibrate.
