Through thick and thin, we love a quick quiz! We think this is one of our hardest quizzes yet. Do you have the knowledge to thin out the clues and get full marks?
#1. Which of these is a chemical found in paper?
Paper is made from cellulose, a chemical that comes from wood, rags, plants and algae.
#2. Which of the following worms is not an animal?
Ringworm is a fungus that infects skin and often makes a ring shape.
#3. Which is the thinnest layer of Earth’s structure?
Earth’s crust is only 15–20 kilometres thick on average, which is only a tiny fraction of Earth’s 6371-kilometre radius.
#4. In which direction do racing sailboats go fastest?
When boats go straight downwind, their wind disappears as they go faster – but a side-on wind stays constant no matter the boat speed!
#5. How thick is the thinnest unsupported sheet of gold ever produced?
Scientists at the University of Leeds created sheets of gold that were only two atoms thick!
