Refining spice in the cooking spice, yes. Chemistry, you dry, you harvest?

 Vitamin C? And the bottle?

Vitamin C is like you do the particular substance in your lab. Like Asprin. Same thing. You concentrate it. Chemistry

Making the bottle? You mean the moding ...to do with high temperature? Or the moding skill, that is vacational school, like you making a glass. But combustion.....that high temperature, it is chemistry process.

The lid, yes

Rotating the lid? Hold it. That is like ... how they design coke early in 90s? The can coke ....no.

That is not chemistry. But the moding....like you are seeing the trajectory, of the lines, or curves,....like you look at into the lid...how do you make those lines, or curving lines?

So moding !!!
