Question ID: 554965
I just visited the CN tower this weekend. When we went through the security archways, we had to wait for bursts of air to hit us while a camera recorded the process. What is the technology and reason behind the bursts of air? I hope the answer will explain the basic principles of this screening tool. sampling air or just displacing clothing to look for concealed weapons are my guesses. I'm sorry but I don't remember the name of the company that makes the archways.

Hello melissatl, Sampling air is essentially correct. These devices, made by Smiths Detection, collect particles from the person's skin and clothes and check for explosives. The following two articles mention the use of these devices at the CN Tower, and describe the basic principles.
