The 475-foot "drop tower" in Bremen, Germany, is not a rocket disguised as a building, but a giant hollow tube used for experimentally dropping things—letting go of objects, watching them plummet toward the ground, and using those nearly 10 seconds of free-fall as a way to study the effects of weightlessness.
Fear not that scientists simply drop lead weights or billiard balls. No—they are much more interesting than that. They also drop fish.
The structure—only 360 feet of which is actually used for dropping—has been put to work with the fantastic goal of "inducing motion sickness in fish," as zoologists R.H. Anken and R. Hilbig explained in a 2004 paper published in Advances in Space Research.
