This officially-licensed Harry Potter Cauldron Light looks (and feels!) like it was plucked directly from one of Snape's potion lessons & let's face it, we could ALL use something a little magical to brighten up our gloomy muggle existence! Powered by batteries or the included USB (Universal Serial Bus) cable, this highly-detailed mini prop contains a bubbling broth that gradually cycles through a spellbinding spectrum of colours. Just take off the lid & pop it back on to switch the light on or off – now that really IS magic.
