What's in this general science quiz?

A good general science quiz for adults asks about the science people meet every day, not the formulas they forgot after school. This pack has 20 science questions with answers: why ice floats and what baking soda is, the heart, brain and skin, India in space from Aryabhata to Chandrayaan-3 and Aditya-L1, and the inventors behind the telephone, penicillin and the web. It is pitched at medium level and takes about 15 minutes live. The first 10 questions and answers are on this page. With a free QG Playground account you can see the full set, add the pack to your quizzes in one click and play it live on a big screen, where players join from their phones with a room code and no app. Ask Granny, the AI assistant, for an extra round on the science behind your own industry.
