|picture of hailstones presumably created by bacteria taken from the BBC article noted below|
This news article on the BBC website mentions recent research findings that suggest bacteria can be the cause for precipitation! That extends the reach of bacteria into a realm that few would have guessed was possible. Go bio! Hmmm..... as a designer challenge, it would be interesting to design a genetically modified bacteria that causes for special hailstone shapes.
1) hailstones that create a whistling sound as they fall
2) hailstones in the shape of an airfoil--with a snowball tip (hopefully a safer design than jarts!)
3) hailstones with a special crystal pattern that reflects various colors of light.
Any ideas? Send me an email at firstname.lastname@example.org
