Repairing Burned-Out Incandescent Globes

Incandescent electric bulbs that have been burned out may be repaired by shaking them, in order to cause the broken ends of the metal filament to strike together. By examining the broken filament one can determine in what direction to shake the globe. The sudden passage of the current upon contact causes an arc at the broken ends of the filament, welding them. A globe thus repaired should be placed in a socket where it will not be given undue disturbance and will then last for a considerable period.
