What is it?

Flowers of frost.

As the water condenses and freezes on to a cold surface it forms these amazing patterns that for all the world can look like fern fronds or flowers or all sorts of things.

There is a good reason why it does so, it has to do with the structure of the ice crystals and has a certain fractalness about it.

I took this on the glass of a cold frame, but the same thing can happen on any cold surface.

Great Dates in Sci and Tech for January.
2nd of January 1860 ~The planet Vulcan is announced in Paris, it did not really exist.

4th of 1643 ~ Isaac Newton was born. So he was a Capricorn.

7th 1610 ~ Galileo discovers the moons of Jupiter

18th 1916 ~ Meteorite hits a house in Missouri

29th 1886 ~ Benz patents the first petrol car.

Something to try.
Dunking biscuits.

Which will survive for longer, what are the variables, design the ultimate dunking biscuit, test your prediction.

There are so many variables but they are so easy to control, what a great may to look at materials

And you can eat the left overs.

Health and safety
Some biscuits may contain nuts.

A good idea
Look for frost patterns.

Hoar frost is where the water freezes straight out of the air and can make the most amazing shapes and patterns.
