From luffas I know nothing. Do you eat them or bath with them?

Hmmm. Only bath as far as I know. They are a cucumber, however, or so I
was told, which led me to believe they would grow much like cucumbers.
I've never seen a luffa that was not a bath sponge. g

http://en.wikipedia.org/wiki/Luffa

The Luffa or Loofah/Lufah are tropical and subtropical annual vines
comprising the genus Luffa. The fruit of at least two species, L.
acutangula and L. aegyptiaca, is grown to be harvested before maturity
and eaten as a vegetable, popular in Asia and Africa . . .

The fruit of L. aegyptiaca may also be allowed to mature and used as a
bath or kitchen sponge after being processed to remove everything but
the network of xylem.
