We have all been there – banging on the end of the ketchup bottle, or desperately squeezing a shampoo bottle until your hand begins to cramp up – just to get the last bits out of the bottle. Seeing remnants of products around the sides and at the bottom of bottles really frustrates me – but luckily some brainiacs at MIT have developed a new super slippery coating for these bottles so that we can get out every last drop!
How does it work?
This technology, patented as ‘LiquiGlide’, is described as a ‘permanently wet, liquid-impregnated surface’. This means that the product inside the bottle will always be directly on top of a layer of liquid, this makes it really slippery – allowing the product to slip out of the bottle with ease. The liquid coating is held to the bottle by a porous solid and the water can cling to the gaps in the solid, you can this this in the diagram below.
You can see LiquiGlide in action here:
Perhaps one day all bottles will be coated with this- and the days of saying ‘stop, you’re not getting any more out of that, just open a new one!’ will be over! (Yes, that’s a direct quote from my Dad).
Till next time,
