The humble microwave: source of hot cups of water, stinky popcorn, and now, apparently, sterile kitchen sponges. A Reuters article recently reported that microwaves are great tools to sterilize bacteria-laden kitchen sponges -- but unfortunately for the not-so-sharp, it turns out that Reuters didn't tell the witless that the sponges should be wet before getting their nuke on. Apparently, more than one person threw his dry sponge into the kitchen microwave only to discover that the thing melted, burnt, stunk up the joint like hot bacteria, and reeked like burnt tires. One more for the Darwin awards. So for the uninitiated: yes, you can throw your kitchen sponge in the microwave for a few minutes to sterilize it. Do make sure it's wet, though, k?
