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!
Yeah maybe I can! Sometimes people call them macaroni crafts and they are made with dry pasta. It's really fun!
You know what would be even more fun? Making macaroni crafts with WET pasta! Think of the fun times you would have!
Hm... I'm not sure how they would stick together. I usually use individual dry pieces of pasta and glue to make a masaic. 
What types of pasta, other than macaroni, have you used? Have you tried cavatappi or bucatini? You should!
I love the Cavatappi! They are my favorite tools to make my art with. They name literally means corkscrew in Italian. 
Which would be cool if you need to make like a futuristic macaroni landscape with corkscrew turns for your macaroni pod racers!!!
I once brought my macaroni art to my local geology club. We usually search for specimens and compare rocks. I thought they would like it because I incorporated from gemstones into the elbow macaroni. They thought it was pretty stange. 
Macaroni and gemstones doesn't sound strange to me. I think that's the combination I've always wanted.
