Drinks outside the Goldilocks Zone

By DannyW

You make a mug of tea or coffee. You get distracted. When you reach for the mug it's dangerously hot or disgustingly cold. A simple stick-like device with a simple colour-coded tip. If the drink is too hot, the tip shows red. If the drink is too cold it shows blue. The Goldilocks Zone, not too hot or cold, shows amber. The deluxe version would have a beeping function to audibly warn you that your drink was approaching 'too cold'.

    Thermochromic paint on mugs would be great for this.
    Thermochromic materials change their colour based on the environment around them.
    In fact; they already exist. http://bit.ly/LiUDDy

    “A simple stick-like device”
    Yeah it’s called a thermometer and has been around for a while…

    I know there are currently companies researching a device that is hand held and able to warm drinks when stuck to the side of a mug. Not exactly what you’re asking but may be something to look out for so you could warm up your drinks should it go cold. Also, I’m not sure how far they are into it so this could be pointless lol.

    sorry to be negative but is it so hard to feel your cup?
    or is this just for lazy people that don’t want to reach for their cup.
    i cant believe this idea is rank 4

    Thermometer is the right idea but needs to be read and the number interpreted. Do you know what a comfortable drinking temperature is?
    As for feeling your cup… it doesn’t work with modern insulated cups. I have some lovely double-wall hot drink glasses at home that are room temeperature outside but contain injury-hot liquids inside. A source of much schadenfreude.

    Also there is a flaw in the plan. Different people like to drink their drinks at different temperatures. Perfect for one may not be perfect for another. My dad likes to drink his tea scaling hot whereas I like it lukewarm as I have a heat sensitive mouth. So yes the stick may show amber, but, it may still be too cold for dad or too hot for me. Plus I can just touch the side of my cup and feel how warm it is or isn’t…

    At the end of the day, coffee is coffee. Personally, I don’t mind either way. If it goes cold then it is my own fault really for not drinking it quicker, but normally I find it still tastes good – especially white coffee!

    There is an audible device in use for blind people so that they dont scald themselves
