Here’s a really fun Halloween DIY that shows you how to make a haunted mirror that will magically let “ghosts” appear.
The mirror is really a box with a two-way mirror on the front. Inside the box are models or other renderings of ghosts. Since the inside of the box is black, the two-way mirror reflects the room normally, but when tiny lights hidden inside the box are illuminated, they wash out the reflection and reveal the hidden ghosts.
