Eric “ALH84001” Archer conducted some testing on the ability of a neon sign transformer to improve beverage enjoyment –

Round 1: Lone Star (the national beer of Texas). 1 cm arc discharge to surface of cold beer for about 15 seconds. Slight foaming occured at the point of arc contact. Panelist 1 (EA) noted the acrid flavor of ozone in the beverage and tossed it over the fence.

Round 2: inexpensive red wine. both electrodes beneath liquid surface, about 10 seconds. transformer hummed but no visible arcing. Panelist 2 (DF) noted a decrease in the “bite” of the wine.
