We’ve seen a boutique line of flash drives that play upon the fact that data is invisible, which means we can’t see their containers being filled up even if they’re already “full” of data. Here’s another take on that amusing dissonance, an empty bottle with a USB drive cork stopper.
Fortunately the Hum Blank USB drive is cheaper than those Empty Memory drives, although it’s still way more expensive than ordinary flash drives, especially considering you’re paying extra for an empty (and small) bottle and a piece of cork. It only comes in 2GB capacity and is available for ¥3,465 (~$43 USD) from Rakuten. I wonder if scientists would find the Hum Blank useful, perhaps store a sample in the bottle and then the data about the sample in the cork.
