Is PLA for 3D printing really biodegradable? I've buried and drowned Benchy for 2 years to find out!

2 years ago, I've burried and drowned a few 3D printed Benchies to see just how biodegradable PLA really is. It's actually much more complicated than you might think.

Special thank you to Stefan from CNC Kitchen for guest appearance! He'll also perform all the tests next year, which I'm very excited for.
