This doesn't quite add up...at least not for aluminum extrusions that Rev sells. A 3"x3"x60" package that weighs 6lb has an average density of 0.011 lb/in3. If that object is made of aluminum (nominal density 0.0975 lb/in3), then it would have to be about 90% air. Even 1"x1" square aluminum tubing with 1/16" wall would be about double that density. But, a large post with a thin wall could make those numbers work. Or even aluminum extrusion with a lot of packing material. Or wiffle balls, or wiffle bats, or any of a number of things that this thread has already mentioned.
