- The most magical heat-changing mug ever
- From black to rainbow at the pour of a kettle
- Stays colourful for as long as your drink stays hot
- Quite mesmerising tbh
They say you can’t have a rainbow without a little rain, and they’re right. Except, in this case, the rain is tea. Or coffee, we’re not fussy.
Pour it up and watch the bleak blackness transform into a glorious technicolour rainbow before your very eyes. And all you need to produce this multi-hued extravaganza is hot water, nothing more. Not even magic extra-sensory rainbow summoning abilities. Science rules.
But this novelty doesn’t come at the cost of quality - this thing is made of the finest sturdy, super durable ceramic with a nice big handle - none of that pinky ring stuff that makes it impossible to carry. Put your feet up, sip into something more magical, and watch a rainbow lightshow unfold before your very eyes.
