Many fine establishments have places under the bar where a lady can hang her purse.
Many do not...but once you buy one of these, you'll be able to hang your purse wherever you choose.
The device is powered by a CO2 cartridge that has one end threaded like the ones used to inflate bicycle tires.
Threading
the cartridge into the central tool to the first stop on the underside of the tool prepares the tool for action.
The top of the tool has a slotted recess that you place one of our special purse hooks into.
Holding the tool firmly against the underside of the bar in one hand, the other hand is used to give a twist to the CO2 cartridge, such that the needle in the tool pierces the end of the cartridge.
The C02 released is harnessed to spin the drive mechanism between the middle of the tool and the the slotted recess on the top containing the purse hook.
In an instant the threads on the purse hook are spun into the wooden underside of the bar, and your purse hook is installed.
Drop the tool into your handbag, hang it from the hook, and look around in puzzlement with your neighbors trying to figure out what that hissing sound was. I guess we could add a device to make it sound like flatulence if you wish, and you could say a loud "EXCUSE me...".
