Ever wondered what Voldemort's bath would look like?  Well one Twitter user has the answer.

A video of a black bath bomb was uploaded to Twitter on Monday and has since become an unexpected viral hit.

Jack Mull tweeted the clip which shows the dark substance being lowered into a bath full of clear water and as soon as the two meet the entire bath turns totally black.

Jack eloquently captioned the video "this bath bomb is some Voldemort sh*t" and once you watch the video it's easy to see why.

Twitter users reacted excitedly to the video which has now been shared 9,000 times.

Some were happy to continue the Harry Potter themed jokes (tbf who doesn't love a good Potter lol?) with Tweets like: "I think you found a horcrux".


While others were just plain worried that the murky water would ink their skin.
