Field guide No. 1521
Upside down starlings in a dry pool
Synchronised flying, inverted.
A flock of starlings flies belly-up through an empty tiled swimming pool, wings spread under the high windows. The pool has been drained, but the lessons are still on.
Field noteBirds can roll for a moment, but a whole flock flying inverted indoors needs a new idea of up.
Also possible, also breaking physics
Cumulus impact in the meadowClouds are mostly air and drift. This one landed hard enough to dig a crater.
Frozen air over an old radiatorIce can form above a radiator when the room is cold. The heating has not been asked.
Floating red stripeA painted red line crosses an empty bowl in mid-air. The paint job outlived the surface.
Sheep with a spiral fleece hollowFleece can be twisted and matted. A spiral this deep implies a sheep with nothing in the middle.
