Why did my hands test positive at the airport?

The Transportation Security Administration randomly swabs passengers' hands at security checkpoints and airport gates to test them for traces of explosives. The TSA swabs are analyzed for nitroglycerin, nitrates, glycerin, or other chemicals. This was an expansion in 2010 from simply swabbing luggage and other items.
