Harry Potter fans can buy their very own invisibility cloak and get up to no good this Christmas .
B&M is selling the cloak which you can use with an app on your phone to make yourself disappear, recreating iconic scenes from the Harry Potter films.
But you'll have to hurry to get your hands on the movie prop because B&M have just knocked down the price from £49.99 to £39.99.
But how does it work?
First you have to download the app to your phone or tablet.
When the patterned side of the invisibility cloak is facing the camera it will be visible on screen.
However, when you flip your cloak inside out, so that the green lining is facing the camera, whatever or whoever is hidden beneath the cloak will magically disappear on screen.
B&M also announced its Black Friday deals with customers able to save up to 60% off branded electrical products.
This year B&M is offering its customers 10 days of deals which will be able available from Friday, November 22 until Monday, December 2.
