Forget what you know about crystals. (LINK)

Researchers have shown that crystals can be so flexible they can be bent repeatedly and even tied up in knots, overhauling our current understanding of the structures, and challenging the very definition of a crystal.

As we learnt in school, crystals are brittle and inelastic - if you try to bend a crystal of rock salt or quartz, for example, it will break. But this new research shows that crystals can actually be made to bend, opening up a whole new class of materials that could revolutionise electronics and technology.

That's just too weird, man!

I have a vague memory of reading that muscle tissue works, in part, due to the crystaline nature of proteins involved which orient differently when the muscle is flexed than when relaxed.

Also, don't quartz crystals for generating piezo-electric work by compressing them unevenly?

And finally, as I weakly remember, the way crystals work to create their own structure and grow is to bend ever so slightly out of alignment, as the molecules self-assemble, sufficiently to end a row of molecules at one layer above the start of that row, in order to be in position to begin at the next layer up. Which is always done at the same angle, and with molecular precision which results in dead flat fracture surfaces, which always cleave at the same gross angle no matter how large the crystal structure. But they can't be perfectly aligned dead flat, or the end of the previous row will never be in position to begin a new row, and a crystaline structure won't ever grow, except in a one molecule wide line.

Has that got anything to do with chemistry?

It's fake chemistry, bigly :p

Crystals, is there anything they can't do?
