my hobbies include rock collecting and making macaroni art. I like to be an amateur geologist. Sometimes people call it "rockhounding" 
You could totally make macaroni art dedicated to showcasing your rock collection!

It is usually scored with lines or ridges ("rigati" in Italian) on the surface. Cavatappi is a type of macaroni, or thick, hollow pasta that is made without using eggs.
