hi prof hwang,

i teacher recently ask me for this
http://ww2.unime.it/dipart/i_fismed/wbt/mirror/ExplrSci/dswmedia/density.htm
to determine density =mass/volume (via water displacement)

is it a good idea to make this in EJS ?
is there any existing EJS that does density =mass/volume (via water displacement) ?

for your consideration :)
