  • I’ve watched a video about this recently. The problem is, most detectors were based on X-rays in the past decades. Liquid explosives are pretty close to the density (and/or other properties) of water, and you can’t tell for sure whether there’s toothpaste or boom juice in that tube.

    However, some airports started using expensive MRI machines that can see stuff in more detail, plus, it lets you to make cross sections from different angles and therefore have a 3D model that you can rotate on your screen (it’s rather cool).

    EDIT: I just realised someone else linked this, too. I would leave it here, it’s still educational.
