Can plants live and grow when “watered” with juice, soda or milk instead of water?


  • Twelve small, easy to grow plants in pots (bean plants work well). Really only four plants are necessary, but it’s good to have the extras in case one or two don’t make it for reasons outside of the experiment.
  • Sharpie for labeling pots
  • A sunny place to keep plants
  • Water
  • Juice
  • Soda
  • Milk
  • Paper and pencil for recording results


  1. Begin with 12 small, healthy plants. Divide them into four groups.
  2. Label three pots each: water, juice, soda, milk.
  3. “Water” the plants daily or as necessary for your climate with one of the four liquids accordingly. Make sure to give every plant the same quantity of liquid.
  4. Check on the plants daily and record your findings in a chart labeled with the date along the left and each of the four liquids along the top. Some possible observations: What color are the plants? How tall are they? Are they getting new leaves? How do they feel (brittle, fleshy)?
  5. Continue the experiment for as long as is necessary/appropriate.
