For a elem teacher science methods class, I recently did the "rubber bones" experiment by soaking a chicken bone in vinegar to remove the calcium. This results in a soft, rubbery, bendable bone. Why then is osteoporosis called "brittle bone" disease, and the loss of calcium results in easily broken bones?
