9v glass

Drinking glasses come in many varieties - pint mugs, shot glasses, highball glasses, red wine glasses, white wine glasses, and even specialist glasses for absinthe, lufienne or ouzo. Curiously, though, none of these glasses involve electricity.

Electricless glasses begone! MaxCo. is moderately delighted to introduce its range of Zapp!™ drinking glasses.

Each Zapp!™ glass has a 9V battery holder in the base. The anode of the battery is connected to a small gold-plated button in the bottom of the glass. The cathode is connected, via a filigree of gold plating, to a gold band that runs around the outside of the glass, a few millimetres below the rim.

The result of all this is that, as you sip your drink, you get that 9V tingle that is otherwise only available by sticking your tongue on battery terminals. Our initial market survey population reported sensations ranging from "unusual" to "odd", but did not unanimously dislike it. We count that as a win.

Inductive Charging Set - 5V @ 500mA max https://www.adafruit.com/product/1407
Half an amp might be overkill. Probably $1 elsewhere. [bigsleep, Feb 03 2019]

Good for one hour of continuous 30V tongue tingling. [bigsleep, Feb 03 2019]

       Is there a direction of potential choice, to clink with other Zapp!™ users?

       So, this gold-plated button, does it extend through the thickness of the glass to contact the drink inside?   

       If not, then no circuit. But if so, then leakage, unless seals, in which case, rubbery/oily aftertaste.   

       ... Oh, all right, silly-cone.

       [pertinax] //button// more a contact glass dress button. Lead acid batteries' electrolyte is open to the air.

       [+] Somebody is just bound to make some of these.   

       In other news a guest was electrocuted at a White House dinner function while reaching for the top glass on a champagne tingle fountain. CNN, over to you.

       9 volt.....? Is there not a version with a mains lead dangling from the bottom for the foolish and daring? (like 8th) {+}

       // does it extend through the thickness of the glass to contact the drink inside?// It does indeed.   

       // if so, then leakage// A wire is set into the stem at the time of manufacture. Once the molten glass has cooled and hardened, the button is soldered on and then both it and the tip of the wire are gold plated.

       What is ' lufienne' please, [Max]?

       //9V battery holder//   

       Just go with a supercapacitor and wireless charger. You could even seal it in with clear resin as the circuit would be ok looking [link].   

       Competition version with bluetooth could allow the voltage to be changed via an app. Technology today is crazy. You can get a miniature programmable bluetooth module for $1 or less.

       // a version with a mains lead //   

       We demand a minimum of a 415V 200A 3-phase supply.

       Especially exciting with high-proof liquors. There’s probably an art to not causing a spark.

       //What is ' lufienne' // It's a sort of schnapps, heavily infused with anise hyssop. It used to be only made illegally and locally, but I believe there is now a commercial brand.   

       //The wires that go through glass when a thermionic valve is made are tungsten// I think you can run other wires through glass. For example, the pins on the bottom of such valves aren't tungsten (or perhaps they're tungsten plated). I know platinum wires can be run through glass - I think the requirements are non-reactivity, wettability by molten glass, and a similar coefficient of expansion to the glass.

Hmm, so you could get tingles in upper lip, tongue, lower lip sequentially, although 50Hz may be a little fast...

       Don't knock it until you've tried it ...

       I wonder if there was a matrix of anodes and cathodes, that could be switched pixelly, forcing electron patterns through the liquor, would the taste change? Sort of cooking in a way.
wjt, Feb 04 2019
  

       Apparently, eating the same food product using utensils made from different materials - such as silver, stainless steel, bronze, wood or plastic - changes the consumer's perception of the taste of the item.

       [8th] I think this was organised by The Institute of Making (well worth visiting, if you're near UCL - you can see their magnificent Materials Library) - see link.
hippo, Feb 04 2019
  

       So the gamut of tastes would be wilder with varying materials and dynamic patterns of potentials. I can now see why Pan Galactic Gargle Blasters have the solid hint of gold brick.
