HANSA International's Hansacanyon Faucet has LEDs that light up with different colors based upon the temperature of the water passing through it. Blue is for cold water, violet for lukewarm and red for hot.
These have been around for years. If found nowhere else, local science museums usually sell them as an add-on spout for around $25. A quick Google... http://dx.com/s/faucet+led+change.html?sort=Price
It's a medieval medical instrument. Used primarily in conjunction with leaches, a barber (the medical practitioners of the medieval) would use this instrument to attempt to dislodge trolls that may have become lodged in the intestines or bowels, thereby causing a significant imbalance in the humors. After treatment, the patient was instructed to eat one live canary whole to scare the dislodged troll, and to sleep on their side on top of a pile of wheat husks for the next two three nights or until they crossed paths with a tall man carrying a caged yellow cat, in which case the treatment was declared a success and the patient would spend the next two weeks suspended upside down in the town square to re-balance their humors.
Its a Chestnut Cracker for those REALLY hard ones to open. You put it inside the cone, put a weight on the top and screw it down. Then BAM! You have very little to eat for a lot of work!

Forget the jack. It's a paperweight, to be used inside a bookcase, for extra pressure. Of course also useable for pressure while glueing things, or leveling the shelves when constructing a bookcase.
