A chemist’s fresh lime soda

I have become a big fan of fresh lime soda over the last four months.

Before India, the closest thing I’ve have to this drink was probably Sprite.

Fresh lime soda is a simple combination of fresh-squeezed lime juice and soda water. You can choose to add sugar, salt, or both to the drink as per your taste.

Personally, I prefer to order my fresh lime soda “sweet and salt”, and trust the masters in the kitchen to add just the right amount of sugar and salt so that the drink ends up tasting very close to a margarita (minus the tequila).

One hotel in Chennai had an interesting twist in how they serve the beverage.

All of the ingredients were provided separately and I was given the task of finding the right combination. (Note: The clear liquid in the top bowl is sugar syrup.)

A great presentation. A needless dirtying of excess dishes. A challenge to find the right ratios to mix.

My hat is off to all the fabulous mixers who have perfected the art of fresh lime soda, sweet and salt.

Mixing Old and New Batteries

Many battery-powered electronic devices come with a warning like this:


Do not mix old and new batteries.  Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium) batteries.

One device I noted this warning on was an automatic card-shuffling device. It seemed entirely out of place, since the machine only used ONE nine-volt battery.

Of course, the advice is sound and should generally be followed.  However, in this case I don’t think the warning necessary, as it would be practically impossible to use multiple batteries at once in this device.

According to Duracell, the reason to avoid mixing old and new batteries is that doing so will reduce overall performance and may cause battery leakage or rupture.  If you’re curious, for a more detailed explanation take a visit here.
