Fallturm Bremen (ZARM Drop Tower)

The Fallturm, operated by the University of Bremen's Center of Applied Space Technology and Microgravity, rises 146 meters over the Universum science center and is one of only a handful of drop towers in the world used for genuine microgravity research, dropping sealed capsules down an evacuated tube to give researchers several seconds of near-weightlessness for experiments in physics, materials science and biology. Public access is limited to pre-booked guided tours of the working research facility, led by staff or graduate researchers who explain both the tower's engineering and the science conducted inside it, including a look at the capsule catapult system installed to double the effective drop time. Tours run only on fixed monthly dates and require advance registration, since capacity is limited and slots fill well ahead of the tour date. A tour runs 75-90 minutes, covering the tower's base, the control area and an explanation of a drop sequence, though visitors do not typically see a live drop unless the schedule coincides with a research run. A recommended minimum age of 12 reflects the technical nature of the content. Admission is cash only on-site, and the tower sits a short walk from the Universum, making the two easy to combine in one outing.
