What you need for the experiment:

  • Large clear cylindrical container – like a drinking glass or vase 
  • Warm water to fill container
  • Wooden spoon – taller than the container for “stirring” the plastics 
  • Table salt or sugar
  • Tablespoon for measuring
  • Variety of empty plastics with recycling numbers from 1 – 7. You do not need all types to complete the experiment. Ask your parent or an adult to help you collect and cut plastics for the experiment. 

Examples to look for:

  • bags for buying fruits and vegetables at the store
  • plastic bottles and caps for beverages, ketchup, and containers for yogurt
  • balloons and straws
