I picked up this cool Tetris mug that changes when hot liquid is poured in it.
It looks empty when there is nothing in it. It’s still a safe game of Tetris. You can see a faint outline of where the pieces will appear when something warmer is is poured in the mug.
I used it with my Keurig machine and it was fun to see the colours slowly fade their way in. When the cup is full of hot liquid the Tetris board is now much fuller and has a higher score of 11,000!
This is 1 of 2 heat-activated mugs (I’ll show you the other one later) but now my morning coffee just got 100x more fun!
