The Roaring Raindrop

Found this article while researching another project. Just thought I would share.

classic motoring history

Funny after testing such promising shapes, MG introduced the MGB in 1962 with pretty much traditional lines with nary a raindrop in sight. I owned an MGB made in 1976 with the same lines. A great little car, but no raindrops still.

About Stirling Moss: I remember watching him drive with a classic straight-arms-to-the-steering wheel stance. I marvel today seeing NASCAR drivers with their elbows-in-the-lap approach to steering. That's progress for you.

Summary:
Contrary to popular belief, raindrops are not tear shaped and are actually shaped like the top of a hamburger bun, round on the top and flat on the bottom. This new video from GPM explains why.

Sorry to be a wet blanket. :)

I'm amazed that this has never come up before in the forum.

News to me.

Now just where did the teardrop shape come from, tears?

SHAPE

The classic shape associated with a drop (with a pointy end in its upper side) comes from the observation of a droplet clinging to a surface. The shape of a drop falling through a gas is actually more or less spherical for drops less than 2 mm in diameter.[9] Larger drops tend to be flatter on the bottom part due to the pressure of the gas they move through.[10] As a result, as drops get larger, a concave depression forms which leads to the eventual breakup of the drop.
