If coffee cups were traffic lights

In the animal kingdom, organisms often use incredibly bright or vibrant colouring in order to visually demonstrate that taking a bite out of one will probably kill you. These primitive evolutionary traits are so effective, that not only do they keep the organisms alive, they warn would be predators that their potential prey probably wont make the best after dinner snack. In some ways, this basic survival mechanism translates into the real world, Traffic lights and stop signs are red to tell us to stop, hazard signs are usually bright red or yellow to garner out immediate attention, and gingers....well, enough said.

Dangerously though, there are still many areas currently where the world doesn't warn us of impending doom. It is a daily ritual for some, and a life source for others, but getting the morning coffee takes the lives of thousands of taste buds at a time and you'll never know when they strike. On one day you'll have the perfectly cooked roast, and the next you will be drinking the molten brimstone that is the run-off from satan's comically sized bath tub.

If only our coffee could warn us about the days when it's feeling a bit tetchy.

Enter the Smart Lid, an incredibly simple device that takes advantage of the technology currently used only on novelty mugs of scantily clad women to change colour when faced with heat. While the sterile white lids of the modern era look nice when we sip our brew in public, they don't warn us in anyway of the veracity of the liquids they supress. A Smart lid however, will start off as brown and turn bright red when faced with heat, at an impressive speed at that!

But surely, this reasonably simple device of unfathomable science will send the cost of my morning hot chocolate through the roof!

No.

 

According to Smart lids, the cost of these new lids would be covered by raising your prices by 1%

Sadly I dont think this will actually fix the problem, as people are only going to order hotter and hotter coffee's just to see exactly how smart their lids are.
