Re: 100 lb of Lead Vs 100 lb of concrete
Add a hundred pounds of cork to your experiment, and it starts to make sense.
The more water something displaces, the more buoyancy it has. The more buoyant it is, the less it "weighs" under water. In this case, the order from most to least buoyant would be cork, then concrete, then lead.
