The humble oil-lamp or diya has been part of our lives for thousands of years, whether for giving light, providing security or for festive celebration. In this Diwali special Chai and Why? session, let's revisit the good old diya. From the materials for the lamp to the fuel that is used, and from the influence of the wick to the properties of the flame, we'll take a look at all the exciting science stories around a simple oil lamp and of course, we'll try some experiments!
Warm greetings for the festive season and best wishes for a healthy, safe and happy Diwali from the Chai and Why? team!
