Airport X-ray

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 438.5 Hz, 6 cents flat of A4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

An airport scanner sends a fan of X-rays through each bag as the belt carries it past, and a row of detectors measures what gets through, one line at a time. Most scanners measure two energies at once. Comparing them tells light elements from heavy ones, so the screen colors each thing by what it is made of: orange for organic matter (clothes, food, paper, plastic), green for mixed and light inorganic matter (glass, ceramics, plastics with fillers), blue for metal, and black where almost nothing gets through.

The bags and the pictures here are built for the splash, with simplified materials. Tap to send the next bag.
