How to Spy Through Frosted Glass With a Piece of Sellotape

A short and simple trick to show you how to see through frosted glass with just a square of sellotape.

Frosting glass is created by sandblasting or acid etching a sheet glass, which distorts the light to create a blurred effect. To counter this you can stick a piece of sellotape on the frosted glass. The sellotape smooths over the sandblasting turning it back to a transparent window.

Hints

• If the glass is frosted on both sides you will need a piece of sellotape both sides.
• The deeper the frosting the less effective this trick will be.
