The On/Off Coffee Mug
In our long list of weird gadgets, I have never came across something like this. A on/off coffee mug to start your day with some fun coffee sipping.
Actually the on/off thing isn’t just for show, pour in a hot drink like tea or coffee and watch it change colour change from black to white, and the text changing from off to on.
When not in use the mug is black when there is no coffee in it or when you put a cold drink in it, it displays the word ‘OFF’ on the front.
The On/Off coffee mug is available to buy online for $28.78 at iWOOT.
LOL, that’s weird. :/
oh wow that is so cool! i need one of those!
