Budding witches and wizards can now dip a cauldron into their bath to discover which of the Harry Potter houses they are destined to join.
The sorting-hat style bath bomb will ooze, fizz and bubble just like a real cauldron and swirl with different colours as it decides whether you are more suited to Gryffindor, Slytherin, Ravenclaw or Hufflepuff.
As you continue to dip the cauldron, the colours will bubble away and a house pin badge will slowly emerge to reveal where you have been sorted.
It only uses natural ingredients, including lavender essential oil which helps promote sleep and calmness - making it ideal for pre-bed time baths.

The bath bomb states it is also safe for children, and promises never stain to stain you or your bath.
Unfortunately, the US-based handmade product doesn't currently deliver to the UK.
The description reads: "Our House Sorting Bath Bomb is PERFECT for Wizards and Witches alike! And the best part... they're all natural AND vegan.
"Inside each cauldron is about 5.5 ounces of skin loving oils, all natural skin sensitive powders, and of course, a PIN that will tell you your house!"

But you don't need to worry if you or the person you are buying it for has already been sorted, as you can request a specific house to be revealed.
The product, which costs £14.25, has racked up rave reviews online, with a five star rating from happy customers.
