This is a single crystal of ice growing into a hexagon shape – like a giant snowflake. Timelapse of about 3 days. (cam pointing into a vacuum chamber in my freezer)

This was quite a long project and I learned more about freezing water ice than I ever wanted to know… if anybody has any questions, ask away! If you want, I’ve also got a [video](https://www.youtube.com/watch?v=L0SYxpVab6M&list=PL39PMIJeIAqyvdfacvam8PtPiS5GO8D__&index=8) with a lot more detail about building the apparatus, with emphasis on WHY the crystals form hexagonal facets when grown this way. If anybody just wants more timelapses, those are [here](https://www.youtube.com/watch?v=MqIvuWsd5OI&list=PL39PMIJeIAqyvdfacvam8PtPiS5GO8D__&index=10)!
TLDW: this ice crystal is growing on a peltier cooler in a vacuum chamber, so the process we are actually observing here is deposition of low-pressure water vapor to solid water.
Hexagons are the bestagons
As someone who does MD simulations of ice Ih crystal growth, it’s pretty neat to see this in real life!
Is this a single crystal?
Eyyyy didnt expect to see you on reddit but this is a perfect fit!
I love your videos so much, they go way more into scientific details than many other science channels. Please keep at it, I love watching your stuff 🙂
Isn’t all clear ice a single crystal, since if it weren’t the light would diffract at the crystal boundaries making the ice cloudy?
What is this, a Fortress of Solitude for ants??
Wandavision is everywhere.
Is this mephisto?
OMG ITS YOU!! hi your really cool
Wow thats look cool
Whoaaa, neat
Hexagons are the bestagons.
So you’re saying it was agatha all along?
A snowflake?
wow so cool
Where snowflake
Very cool! But allow me to be pedantic: shouldn’t this be in r/physics? Is a change of physical state, not a chemical reaction (water stays water). Post it there and you may get more appreciation.
