How to make it:

1. Start by putting a 1-centimetre-deep layer of soil at the bottom of your plastic box. Then add a layer of sand about 1 centimetre deep. Repeat this process, alternating between soil and sand until there is a space of about 5 centimetres left at the top.

2. Add a layer of leaves, followed by vegetable peelings, overripe fruit and tea leaves. Add your worms!

5. Place some cling film over the top and secure it in place with an elastic band – this will stop your worms from wriggling out! Don’t forget to poke some air holes in the cling film so that the worms can breathe.

7. Put the box somewhere cool and dark. Check every day to see whether your worms have eaten the food and to look at the patterns they’ve made using the soil and sand. Make sure you keep the soil nice and moist by adding water.
