So you won't have spotted them (yet) in the UK, but over in America Starbucks was turning heads earlier this month with new colour-changing reusable cups. And they went down a storm.
The reusable cups change colour when filled with cold drinks and come in packs of five and include five cups with matching lids and reusable straws. The cups were so popular that people were trawling the Starbucks chains all over to buy them, with some consumers reselling them online for over 8 times the price. People really loved those cups!
Send us a picture of your Starbucks cups if you managed to get your hands on any over on Twitter.
