You will Need
- Strips of news paper
- Blood & Bone (garden fertilizer)
- Bread
- Grated Carrot
- Grated Potato
- Soil
- Two or Three 2.25 Lt cold drink bottles (we used Coke bottles)
- Clean the plastic bottles well. Cut the bottle around the top leaving a small part to act as a hinge.
- You will need fruit, vegetables, soil, paper and fertilizer. In order to make all the bottles identical I chose to grate carrots and vegetables and use a cup measure when placing into the bottles.
- Follow the recipe (a picture recipe)
- Layer soil, vegetables, fertilizer (only a tablespoon per layer) and paper. Each bottle needs to be identical.
- Spray each layer with a little bit of water. Do NOT soak. Only a fine mist spray.
- The original experiment required two identical bottles. We made a third bottle without fertilizer because we wanted to know how well compost worms work in comparison to fertilizer in a compost bin.
- When the bottles are full tape them shut.
- Mark the side of the bottle with a permanent pen showing the different layers.
- Place one bottle on the windowsill, and one in a dark cupboard. We placed the one with the worms in the dark cupboard as well.
