I think they have use as a tool apparatus. And also precision workmanship.
And like alchemy. Is it really worth the energy used for the energy produced. !
If it costs more effort it's not worth it. However, they serve the purpose they
are invested in.
But I am still all for alchemy !!!
And I love crystals and had a collection of them at one time. Outside.
Oh yes, and thank you for the video. Lol. Love it .. interesting. ..
