Learn the science behind your soda’s sparkle and how to avoid too many bubbles

Pop, soda, fizzy or soft drinks. Whatever you call them, there’s nothing better than sitting out in the garden and sipping a nice, cool drink of cola or lemonade. But have you noticed that some drinks are fizzier than others? Or ever wondered why drinks don’t appear fizzy in a bottle, and only start to foam once you open them? The answers, of course, are to do with chemistry. Read this article and watch the TikTok to quench your thirst for knowledge. And use this everyday example of equilibrium in your science lessons.
