Oh, really? What did you find out?

That makes sense! It's cool to know that art can be so technical.

Have you ever worked with a castable material for your projects?

I haven't tried it yet, but it sounds interesting!

Yeah, it’s really fun to experiment with different castable substances.
Root Explanation
Castable → It is formed from "cast" (from Old English "castian", meaning to throw or to hurl) and "-able" (meaning capable of being). The word "castable" means capable of being thrown or shaped into a particular form.
Memory Tip
Think of something that is 'capable of being thrown' — 'cast' means to throw, and '-able' indicates the ability to do so.
