Recreated from a series of drawings recovered by archaeologists from an undisclosed site in central Italy, and suspected to have been created by a cousin of Leonardo da Vinci, the Tuscany Twister appears to have originated as an early attempt to develop the world's first ultralight aircraft.
CAUTION: Extensive testing has since shown that, when constructed form wood, friction-generated heat will cause the apparatus to burst into flames long before achieving the lift necessary to free a person from gravity's grip.
The attached notes, however, indicate that it was used extensively as a magicians' utility prop during the Renaissance. The propeller will reverse its rotation at the operator's whim, allowing it to be used as a lie detector, a means to locate a lost playing card, or anywhere else it might be useful.
It may also lend itself to any number of other purposes as diverse as keeping cool on a hot summer day, or keeping biting insects at bay.
Although its only limits are the operator's imagination,, users are strongly cautioned against attempting to use it for levitation, due to the previously mentioned fire danger.
No batteries necessary. Variable speed, reversing.
