This ignores the weight of the cardboard center, you have to subtract
that out too. Amazing how easy it is to screw up a simple task.
Imagine doing something really hard like sending a vehicle through the
atmosphere, accelerate to 18,000 miles an hour, bring it down just at
the right angle to avoid burning up or skipping out into space, and
surviving the heat of reentry to land safely.

The International Space Station (ISS) most important legacy may be
jump-starting space tourism. Consider: the first space tourist, Dennis
Tito, was supposed to go to the Soviet era Mir space station. Under
pressure from NASA, Russia de-orbited the Mir which resulted in Mr.
Tito going to the ISS instead. Now the Mir was old, smelly, crowded and
probably not all that nice. The ISS was brand new, shinny, much more
roomy, etc. Mr. Tito came back to Earth with glowing accounts of how
great space is. Would his experience have been as good on Mir?
