Bottle Method: Initial Stages of the Process
- Choose the Right Bottle: Begin with an empty plastic bottle, preferably transparent and plasticized for optimal visibility of its interior.
- Prepare the Bottle: Remove the label from the bottle, and using a cutter, carefully cut around the central part, dividing it into upper and lower sections.
- Create Holes: Light a candle and heat a metal tip (knife or nail). Use the heated tip to pierce the cap of the upper part of the bottle, creating holes for ventilation.
