It’s just like putting a message in a bottle, except it’s a message file. This USB Bottle Drive is a flash drive in a removable cork. It would be pretty pointless if it wasn’t removable- break glass in case of emergency I guess.
Now I suppose you could put some liquid in the bottle or use the cork on a wine bottle but that would probably ruin the flash drive if it’s not kept upright. I can’t find any studies on the effects of wine on a USB flash drive but instinct tells me it would be catastrophic (ruining both the drive and *gasp* the wine). It reminds me of that great song by The Police- you know, “So Lonely”. Love that one.
