When I was a kid, our science teacher once brought a beaker and some chemical substances in the classroom. She said she could put some not-so-good looking chemicals into water and mix them to create Coca Cola. What she said sounded very interesting and we all sat straight on our seats to see water turned black into Coca Cola. She then asked us to taste the liquid and it really felt like Coca Cola. You usually don't get teachers who do things in class that students find interesting. That day, she taught us an important lesson that everything in this world, at the end of the day, could be created by mixing the right set of substances. I never saw the world the same way again. I really wanted to become a scientist to do fun things like her. What is your childhood's maths or science story that inspired you most? Shared via Athar Osama
