I admit that I only ever understood the simpler math on fluid dynamics, but I -am- a big fan of setting up a ripple tank and just playing with it.
All pendants come with the chain with which they are pictured. Most chains are about 17inches long, and will fall about midway between the neck and the decolletage on an average woman. We realize that measurement is a bit biased; our pendants are unisex and we are happy to provide longer chains if desired.
