How to Make Soda Bottle Greenhouse
This soda bottle greenhouse offers a simple, engaging way to support science learning, responsibility and hands-on exploration while watching plants grow from seed to sprout.
Step 1: Cut the middle section out of a clean 2-liter bottle and discard it. Cut small drainage holes in the bottom portion. Make sure the top portion fits into the bottom to form a greenhouse.
Step 2: Fill the bottom portion with soil. Poke one to three small holes in the soil and place a seed into each hole. Lightly spray the soil with water.
Step 3: Cover the top portion of the bottle with plastic wrap and secure it with a rubber band. Place the bottle lid on top to complete the greenhouse.
Step 4: Set the mini greenhouse on a sunny windowsill, using a tray underneath if desired.
Step 5: Observe over several days as seeds sprout. If seeds do not sprout, try planting new ones.
Step 6: Once seedlings grow tall enough, transfer them to a larger container or outdoor garden.
