Is is a tear drop like artists draw it.
Raindrops are circular, or round, as they fall through the air.
They may jiggle around a little and be more oval shaped sometimes, but they are not shaped like a teardrop. As the water builds up it gets heavier and heavier. This causes the water to dangle down a bit, but it is still holding on to all the other water in the faucet. As it falls, less and less of the water in the drop is hanging on to the water in the faucet, causing the pinched off teardrop shape artists like so much. Below is a picture showing how the teardrop forms.
