Episode 2 of my series on water ice! Admittedly this is probably the least interesting because it's some negative results, but it's not very scientific to only discuss successes right? In this video, I use a lens to melt ice from the inside out, exposing it's polycrystalline structure (and explain how it's different from a single crystal). With this partially-melted ice, I can do a bit of materials forensics, and actually figure out how it formed, hopefully so I can improve the process in the future!

Next video will be on vapor growth, and I'll say right now that it DOES work to grow centimeters-big faceted single crystals! Subscribe to make sure you see it!
