At home, if people are washing their hands as often as they should, a soap dispenser doesn't have enough time to build up enough water loving bacteria.
Lists of potential applications include oil lanterns, soap dispensers, terrariums, drinking glasses, speakers, vases, planters, and snow globes, in addition to food and drink storage.
This, says the advert's urgent voice-over, protects you from the "hundreds of bacteria" you can pick up when touching the "germy pump" of a conventional soap dispenser.
