Materials required

  • Big Plastic Bottles 2 ltrs
  • Long String or cotton thread
  • Soil and manure
  • Pair of scissors
  • Sharp object to make a hole in the bottle cap


First of all, cut the plastic bottle you have collected into two parts with the help of the scissors. You may take a 2-liter mineral water bottle or even a big soft drink bottle for the purpose. You can cut the bottle into two parts; make the upper part slightly smaller to ensure proper balancing. But be very careful while cutting the bottles. Take the help of some elders for the purpose. Check that the rim is smooth and even.

For our purpose let us name the upper portion of the bottle as 'A' and the lower portion as 'B'. Now fill the lower portion (B) of the bottle with water. Do not fill it to the rim. Leave enough space at the top.

Now make a hole on the bottle cap with the sharp object. A needle or a nail can be used for the purpose. Take the cotton thread and make it pass through the hole. Now put the cap back at its place i.e. at the mouth of the bottle. Place the upper portion (A) of the bottle upside down on B to check that the thread reaches the water portion appropriately. The thread should also be long enough to be inside A.

After checking the length of the thread, you may take the A and fill it up with soil and earth. Also, you may add a little manure if you wish to. Ensure that the thread remains between the layers of the soil and not just at the bottom of the soil.

This way, the plant in A will receive the water from B through the thread. The soil in A will remain damp as long as it gets the water. The plant will also not get withered. This can go on for 4-5 days.
