Bottle 911 - Working Clocks in a Light Bulb
Date Added: 03 May 2011

This is a completely functional assembly of two clock movements inside a 1,000 Watt light bulb. All of the components are inserted through a hole at the base of the bulb that is 1 inch in diameter. The bulb has the typical shape of an incandescent lamp. It is 6 and one half inches in diameter and 12 inches tall. The dials of the two clocks are 4 inches in diameter and the two back-to-back movements are 2 inches deep. The clocks are supported by a central support column made of brass tubing that is then mounted to a support bracket fastened with allen screws to a brass ring soldered to the inside of the base of the bulb. The assembly of the clocks inside the light bulb requires some special made tools to mechanically connect the components. The two movements are assembled inside the bulb and then fastened together back to back with allen screws. The two movements are quartz movements with a shared quartz module and battery supply, hidden in the base of the bulb. The movements can be adjusted time-wise by a long shaft that is enclosed in the support column and can be engaged with the time adjusting knobs in each movement. The base for the light bulb clock when finished will be made from a solid block of clear acrylic 4 inches thick and 12 inches in diameter with a threaded socket turned into the base, allowing the bulb to be screwed into the base as you would with a normal light bulb.
