1. An apparatus comprising:
a pump having a pump stem extending from a top surface thereof, the pump stem having a liquid dispensing opening and being normally biased in an upward position, the pump being constructed such that manual depression of the pump stem and subsequent release causes liquid to be dispensed from said liquid dispensing opening;
a solenoid coil positioned outside of and above the pump and outside of and above the pump stem;
a hollow liquid conducting plunger positioned within the solenoid coil and configured to interconnect with the pump stem so as to receive liquid to be dispensed from the liquid dispensing opening of the pump stem and having a ferromagnetic portion positioned thereon, the hollow liquid conducting plunger having a liquid dispensing opening located at a top end thereof; and
the solenoid coil and the plunger being so configured that pulsing the solenoid coil with electrical current drives the plunger and pump stem down thereby causing liquid to be dispensed out of the liquid dispensing opening of the hollow liquid conducting plunger.
