How can I plant an avocado seed in water?

To plant an avocado seed in water, first clean the seed and insert three toothpicks around its middle. Place the seed in a glass of water with the pointed end facing up. Change the water every few days and wait for roots to grow. Once the roots are about 2-3 inches long, transplant the seed into a pot with soil. Keep the soil moist and place the pot in a sunny spot.
