On first glance, this nifty colour-changing mug looks like an ordinary black receptacle for all your hot drink needs, but pour in some hot water and a remarkable change occurs. As the mug fills with hot water it gradually reveals the rather self-explanatory message, 'Hot Stuff'. Which is exactly what you'll feel like when you're drinking your morning coffee from it.

Not only that, but it'll also let you know if your drink's gone cold, and it makes a great gift for someone in your office.


  • Colour-changing mug that displays the words 'Hot Stuff'
  • Great for seeing if your hot drink is still hot
  • Perfect gift for office colleagues
  • Suitable for ages 8 years +


  • H: 9.6 W: 12.5 D: 8.2 cm

Hot STuff Mug

I bought this to give my student nephew for his Christmas. It changes colour with hot liquids so appeals to anyone who gets bored with the usual mugs.

Bobbly cup

The Hot Stuff Mug was okay after a few times using the cup but washed it up on the 4th time and the cup went a bit bobbly with bubbles like I've burnt it. It's still useable.

Review of Hot Stuff Mug

I was getting the I Love Spreadsheet mug for a colleague and saw the Hot Stuff one. I needed a new mug so treated myself to this one. We have good laughs when someone offers to make me tea then comes back and says 'your cup was black, wasn't it? It confuses them.

Does what it says!

The Hot Stuff Mug is a good sized mug. It does exactly what it says and changes to read "Hot Stuff" when hot water is added!

Doesn't last............

Works great but within a couple of weeks of use the heat activated shrink wrapping is cracking and falling apart, rubbish.

Briliant buy!

I love my new Hot Stuff Mug. When my colleague offered to make me a cuppa, she was so surprised when it changed colour and the lettering 'HOT STUFF' came up. We now have HOT STUFF and I LOVE SPREADSHEETS sitting side by side on our desks!

Very nice mug

Fantastic service and well packaged. This mug works exactly as described, changing within seconds of hot water being added, rising up untill the whole mug has changed. Once changed, the 'Hot Stuff' lettering is very clear. Nice sized mug too.
