A video clip shot yesterday at Columbus Ohio Airport illustrates how the Transportation Security Administration has dreamed up a bizarre new way to waste time and taxpayer dollars – by testing drinks purchased by travelers for explosives inside the airport long after they have already passed security. 

The footage shows TSA agents walking around a departure lounge asking to test passengers’ drinks for explosive residue with a swab they hold over the liquid.

“Now remember that this is inside the terminal, well beyond the security check and purchased inside the terminal…just people waiting to get on the plane,” writes the You Tube user who uploaded the video.

“My wife and son came back from a coffee shop just around the corner, then we were approached. I asked them what they were doing. One of the TSA ladies said that they were checking for explosive chemicals (as we are drinking them).
