Making things glow in the dark

Have you ever wondered what makes certain things glow under black lights?
For this experiment you will need:
• a black light• petroleum jelly
• a piece of paper
First we’ll use the petroleum jelly as a kind of invisible ink. Dip your finger into the jelly, then use your finger to write a message on the piece of paper. Use more jelly if you need to – but this probably isn’t the time to write a long speech! When you’re finished, wipe any remaining jelly off your finger. Have the black light ready, then turn off the room lights and turn on the black light.

How to make lumia box?
The Lumia Box
What is a Lumia Box?A lumia box is also known as a "camera obscura". The words
camera obscura mean "dark room" in Latin. Some camera
obscuras are really the size of a room; you actually get inside,
and look at images on the wall coming from either a hole or a lens
on the opposite side of the room.I call this project a lumia box
because the purpose is not simply to look at images of the world
, but to create unusual images of pure light. "Lumia" historically
are kinetic-art sculptures that create patterns of moving, vibrant colour.
This simple box makes that possible......
