Joseph Wright of Derby, an English painter who loved science and the drama of candlelight.
A traveling scientist shows a family a science experiment at night, using an air pump and a glass globe with a little bird inside.
Painted in 1768, it captures a time when families gathered to watch exciting new science demonstrations for fun and learning.
A single glowing light in the middle lights up every face, a dramatic effect called chiaroscuro.
Look at the different faces: some watch with wonder, some look worried about the bird, and the scientist waits at the pump.
You can see it at the National Gallery in London, England, where it is one of the most loved paintings.
The scientist looks straight out at us, as if inviting you, the viewer, to decide how the experiment should end.
