Step by step

  1. Make sure the milk bottle has been washed thoroughly with hot soapy water to get rid of any milk and the milky smell. 
  2. Place the lid onto a wooden board and use a hammer and nail to make holes into the lid (adult help may be required). Smaller nails will create smaller holes for a finer spray.
  3. Pop one small hole in the handle of the bottle to allow air to get in. This will help the water flow.
  4. Decorate the bottle with permenant pens. Make sure the outside of the bottle is competely dry before you do.
  5. Fill the bottle with water and replace the lid.
  6. Get watering!

Hints & tips

  • Smaller 1 pint bottles are perfect for small hands and 2 or 4 pint bottles are great for older children.
  • Different sized nails will produce varying sized holes e.g. smaller nails will create a finer spray which is ideal for seeds and seedlings. Larger holes can be used to water more established plants.
  • You could make up several watering cans with different sized holes in for different uses.
