Nothing beats an ice-cool refreshing lemonade on a hot day. But what if the only beverage you have is cold water?

Well, a group of Singaporean researchers from NUS have figured out a way to replicate its taste — using the power of the internet and electronic tumblers.

First, the team measured the colour and the acidity level of an actual lemonade using an RGB colour sensor and a PH level sensor.

This data is then transmitted over the internet to a tumbler outfitted with an electrode. This electrode, which is placed on the rim of the tumbler, sends out electrical signals to the drinker’s taste buds, simulating the sour taste of a lemonade.

On top of that, LED lights placed inside the tumbler changes its colour to that of the lemonade.

The replicated lemonade does not contain the full flavour of the real McCoy — testers said the fake lemonade tasted less sour than the original version.

Still, at least you do not have to worry about high sugar content.

The researchers, led by Nimesha Ranasinghe, have been working on this technology since 2013. Previously, they developed electrodes that could simulate salty, bitter and sour tastes.

The team plans to simulate the taste of cocktails in the future. But if they don’t get you tipsy, then what is the point?
