You will need a camera flash.
Go in to a dark room turn out all the lights and wait for your eyes to
adjust (about 20 to 30 minutes). turn on the flash and when it's ready
place the lens of the flash on the under side of your arm look at you arm
where the lens is. close your eyes and fire the flash and the instant you
see the flash move the flash and open your eyes while still looking where
the lens was and you will see a phosphorescent glow in the shape of the
lens on you arm for several seconds the color will be yellowish green.
