British tourists issued warning over two-way mirrors in hotel rooms | Travel News | Travel

Britons staying in hotels have been urged to check if their mirror is functioning both ways before settling in.

Although two-way mirrors are very rare, some social media users have shared stories of finding one in their hotel, B&B or holiday let.

A mirror expert has shared how holidaymakers can test if their mirror is two-way. John Cutts, founder of MeandMyGlass.co.uk, said: “The thought of someone using a mirror to spy on guests is disturbing, to say the least.

“The good news is there are multiple ways you can check for a two-way mirror when staying in a hotel, motel or B&B.”

John shared his best five tips to find out if a mirror could be functioning both ways.

The fingernail test

Place your fingernail onto the mirror, if there is no gap in between your finger and its reflection, it could indicate a two-way mirror. On a regular mirror, there will be a gap between your fingernail and its reflection.

The tap test

Noise is a huge factor in identifying whether a mirror is two-way. Give the glass a tap around all four corners and in the centre. If it makes a hollow sound, there’s a high possibility there’s something on the other side.

Use a phone flashlight

When you stand and face a mirror, shine a flashlight on the glass and see if the light reflects back at you.

If it doesn’t bounce back, then the light will shine through on a two-way mirror to reveal what’s behind the glass.

Look at the installation

If the mirror is hanging then it is very unlikely it is a two-way mirror. Two-way mirrors tend to be part of and set into the wall as opposed to just hanging on it.

Closely check the reflection

Place your face against the mirror with your hands beside your head, blocking out any light. If the mirror is two-way, you may be able to see straight through.
