Contrary to what the name and form factor might suggest, the Aladdin Vaporizer was not a tool to help you get high. Instead, according to one enthusiast of all things Aladdin, the device was used to make insects vanish.
Aladdin Magic Vaporizer, kills insects, with original instructions found by Bill & Treva Courter. Made by M & M Mfg. Co., Amarillo, Texas. No date. "Use the vapor method to control many annoying insects, such as flies, mosquitoes, gnats and other small flying insects." One capsule treats 1000 cubic feet.
I shudder to think what sort of gas was used in this thing, and whether or not people sat in the room while the vaporizer was at work, but if you want to own a bizarre piece of the past, the Aladdin Magic Vaporizer can be yours on Etsy for $22. [Etsy, Aladdin Knights]
