NOW TRY THIS

SEE YOURSELF AS A “GHOST”

When you look out of the window during the day,

you can see what’s outside, but at night you only see

your reflection. You don’t see your reflection in the

day because it’s much fainter than the light outside.

However, at a certain time between day and night—

around dusk—you’ll see your reflection and what’s

outside mixed together. You will look like a ghost!

HOW DID IT WORK?

Windows are made of

glass because glass is

see-through. However,

glass is also a little like a

mirror—it reflects things.

By arranging the light,

glass, and mirrors in a

certain way, the audience

sees a reflection of an

actor under the stage.

to be a ghost.

Mirrored glass redirects

ghost image to the stage and

also enables audience to see

it through the glass.
