Remove the stone from the Avocado. Peel, yes that what I said, very gently peel the brown thin hard layer of the seed with a sharp vegetable knife or alike.
Put 3 toothpicks into the stone, not more than 2 mm, that way you can place it over a glass.
Fill up the glass with water until the stone just touches the surface of the water.
And now we wait...
And now we wait...
