Colour Changing Cups
The future has arrived (with a distinct touch of the 90s). The first of their kind in Australia, REDDS Hyper Colour cups change colour when cold. Yellow changes to Green and Blue changes to Purple.
Remember for a reaction to occur, it must be a cold drink (4°C), so make sure it is straight out of the fridge or with ice.
These cups are 100% recyclable and BPA free.
