I am interested in building an exhibit similar to the "Touch the Spring"
display. Unforunately, I am having difficulty locating a scientific
supply house that sells such a large concave mirror (16 in, 40 cm), for
a price of around $40 as mentioned. Could someone please refer me via
email to such a supply house?

Thank you,
Robert Weatherby
