Toys from Discarded Lamp Bulbs
Spectacular Fireworks Amuse and delight the kiddies by hooking a lamp in which the filament has been broken in circuit with a spark coil. Brilliant, weird, light results.
Gravity Experiment To prove that cold air weighs more than warm, heat the air in one of two carefully balanced bulbs from which the tips have been broken. The cold end will sink.
Spouting Fountain Hold a lamp under the water and break the tip off. A tinkling rush of water will spout into the bulb until the vacuum has been replaced with liquid. If you want a surprise, try this with ginger ale!
South Sea Sailboat By binding three bulbs together a craft can be readily improvised after the manner of a catamaran, which will sail well and please the youngsters.
Solving the problem of what to do with old bulbs!
