Every once in a while I come across an art project from recycled materials that really makes me pause and say, "Wow!" If you click on the article, "An Artist's Visionary Plastic Bottle Sculptures Offer A New Perspective On Garbage," you'll see a virtual cactus garden made by Veronika Richterová, an artist from the Czech Republic. Her medium is plastic soda bottles!
Click on the artist's website. The photos of brown bottle bats and a green bottle crocodile, will astound you, too!
Some people might ask if what we're looking at is really "art." That's a question that is addressed in one in a series of books for kids called, But Is It Art?: Junk Sculpture by Alix Wood [J 731.2 WOO]. "What is art?" has been discussed for decades, and will continue to be discussed--probably forever!
If you want to get creative with recyclables, then I'd recommend spending time on Pinterest and using "art from recyclable materials" as your search term. There are dozens of boards and thousands of projects to explore!
We also have plenty of books to get you started, too, especially in the children's room. One such title is Organic Crafts: 75 Earth-Friendly Art Activities by Kimberly Monaghan [J 745.5 MON].
