Slytherin Magic Meter House Detection Monitor

The Slytherin Magic Meter House Detection Glass is a unique and interactive collectible inspired by the ambition and cunning of Slytherin from Harry Potter.

Make sure your hands are warm. 

Simply place the meter in the palm of your hand and grip it lightly.

The coloured liquid inside the monitor will magically react to your hand and the liquid will rise.

If you're a Slytherin, the liquid will flow quickly to the top and 'boil' over. 

You'll see the liquid bubbling way, you're a Slytherin.

If the rise is slow, then try one of the other meters to determine which house you belong to.

A must have for any aspiring Witch or Wizard.
