Something that is bad for us in high doses may be beneficial in low doses?! Next they'll be telling us that exposure to radiation and toxins can help cure cancer, or that the same stuff that rusts away unprotected steel and iron is actually necessary for animal life!

Using Aluminum Oxide Paint To Secure Wi-Fi 271

eldavojohn writes "The BBC reports on people using aluminum oxide in their paint to block Wi-Fi signals from leaving their home or business. Aluminum oxide resonates at the same frequency as Wi-Fi signals and other radio waves, blocking data from going outside a building. It's not a flawless solution, as it may also block AM/FM signals. You or your neighbors may be unwittingly using this already, as most pre-finished wood flooring uses aluminum oxide as a protective coating."
