If you are simmering in the hot Hyderabad heat, go and read Navin’s post about the various street-side delicacies that might just have the right cure for you:

A goli soda comes in a green bottle, and is sealed by a glass marble (the eponymous ‘goli’). The marble has to be pushed in to open the bottle. How a goli soda bottle is opened is half the fun. The boring way is to use an opener – shaped like a bottle cap with a small cylinder jutting from it. This is kept on the marble and pressed, pushing in the marble and opening the bottle. The cool way to open it is to put your thumb or index finger on the marble, bent at the first joint, and smashing it with the heel of your other hand. This opens the bottle with a satisfying pop, and you try to look very cool as you ignore the throbbing pain in your finger (or thumb) as you down the soda!
