this is truly a golden experiment in chemistry.
you require acetone, a glass rod, nichrome wire and a piece of copper. first pour acetone
in a large beaker. then take a piece of copper plate and hang it by a nichrome wire. place
this nichrome wire in a solid glass rod. hold the rod and heat the piece of copper in a
bunsen burner until it begins to glow. place this in acetone beaker. the plate must not
touch the acetone. after some time you will find that the copper is glowing, scintillating.
it looks great. it looks golden. this is because the fumes of acetone come in contact with
the hot copper plate and make it golden. as the temperature of the copper plate goes down
this phenomenon of glowing also fails. in the end you can pick up the glass rod and
as the copper plate comes out it becomes green and tarnished.
