For those who have everything: TCA-3 coffee siphon

It may look like a contraption that belongs in Dr. Frankenstein’s lab, but the TCA-3 coffee siphon from Hario makes “the most deeply nuanced” java you’ll ever drink. Water is boiled in the lower globe over a butane burner, causing it to rise into the tumbler above, where freshly ground coffee awaits. The grounds should be stirred before the liquid begins trickling downward again. For “everyday caffeine fiends,” K-Cups should do; this device is for true devotees.
