Another entry in the annals of impractical barware. For a measly $229 you too can buy one single cup that floats when plugged into power and suspended above a single specific coaster. Great trick, and the video of someone walking while holding one of the wireless versions is sure neat. Would be more neat if the wireless wasn’t the size of a brick.
Within reason these are neat but there is just too much going on here for this to be anything other than a newton’s cradle for drinkers with more money than good sense.
