Brown wants to try to raise an obelisk using a method similar
to the one that Hopkins experimented with in Egypt. He builds
a small sandbox to test the theory that ancient
obelisk-builders used millions of grains of sand to lower
their granite monuments into position.
In Egypt, Hopkins removed sand in the pit by hand, a method
some felt was risky. Brown plans to build an enormous sandbox
with holes in its side that can drain the sand, eliminating
the need to get into the sandbox with a moving granite
obelisk.
One of the keys, Brown believes, is to use dry rather than wet
sand, so it flows freely. His team's attempt will be the first
ever to use the sandpit method to erect a large-scale obelisk
in modern times.
