This quiz is all about fibres. From fabric to food, there’s plenty of fibre to chew over!

#1. True or false? Carbon fibres are usually a bit thicker than human hairs.

False. You can fit about 100 carbon fibres side by side in a millimetre, but only about 10 human hairs.

#2. How is T-shirt fabric made?

T-shirts are usually made from knitted cloth.

#3. Which of the following comes from a plant?

Linen is made from the fibres of the flax plant. Cashmere and mohair are both goat hair, and angora comes from rabbits!

#4. What kind of signals are sent through an optical fibre?

Optical fibres are thin strands of glass or plastic that carry light signals. They work over longer distances than wires do, and they aren’t affected by magnets or mobile phone signals.

#5. Which part of your digestive system absorbs dietary fibre?

Dietary fibre is a part of plant-based food that your body can’t digest. It helps to keep your digestive system healthy
