Kaleidoscope Black Eye Gag is a little kaleidoscope with a practical joke twist.
This is a working kaleidoscope but when the person puts it to their eye it leaves a black ring.
The victim will have no idea they have a black eye until they look in a mirror.
The black eye is created by a harmless powder which washes off.
An old classic which is great fun"
