The Skylab experiment spider cage. This is not the actual flown experiment
box, but is described as "identical to the ED52 web formation experiment
apparatus" (NASM collections ID #A19740484002).
The accompanying sign reads
Spider Web Formation Experiment
One of 19 student experiments aboard the Skylab space station in 1973 examined
spider web formation in zero gravity. Astronauts monitored the activity of
spiders released into this box. At first their webs were rather sloppy, but
they soon became more regular as the spiders adapted to weightlessness.
