Leave up to a Kiwi kid to design a product specifically made for bottled cold beverages. I don’t imagine your beer would become combustible(?), Besides that’s what R&D is for. At -173 degrees I wouldn’t use it without gloves. But how exciting! 10 seconds. This has a practical commercial use in bars and restaurants as well. I hear, “My pinot grigio has become warm while I was on the phone with the Baby-sitter, You got any ice?” I’m excited. I can sell this gizmo in the states and retire in a year. I got 5000 applications. I’ll take 500 right now.
