A wormery is a type of closed composter that uses worms to turn kitchen scraps into a valuable soil additive and liquid fertiliser called worm tea.  Did you know that compost worms can eat about half their body weight in food waste in one day? If you'd like to build a wormery for your classroom or home, here's how to do it. 

You will need:

• Our instruction and activity sheet (pdf)
• Two plastic boxes that fit together. The top box needs a lid.
• An electric drill or awl for punching holes (with supervision)
• Kitchen waste and/or a small amount of garden waste
• Plenty of newspaper or cardboard
• Compost or soil
• Worms! - Tiger Worms (Eisenia fetida) are best
• Two bricks, or something of a similar height
• Optional - a tap attachment for collecting worm tea
