1. An electronic wand adapted to be held in the hand comprising:

  • a rod-like body provided with a hollow base at one end thereof and a light emitting diode at the opposite end thereof, said base defining a handle capable of being grasped by the hand; and

    an electronic circuit in said base and electrically coupled with said light emitting diode, said circuit including a multivibrator having an output signal capable of oscillating at operating frequency to cause the light emitting diode to flash, said base having a pair of spaced terminals thereon coupled to the circuit, said terminals being bridged by the palm of the hand when the handle is grasped so that the palm provides a resistance forming part of the circuit, said resistance being variable as a function of hand pressure to cause a change in the frequency of flashing of the light emitting diode.
