Apple does a ton of stuff behind the scenes to make their products, and even their campuses, as environmentally friendly as possible.  You might already know that they recycle rare metals like tin and aluminum—but did you know that they manufacture their own synthetic sweat? Or that they place their solar panels out of reach so yaks won't eat them? 

So, to celebrate Earth Day, we asked the “crazy ones” in Apple's health, environment, and toxicology department some pretty crazy questions in a campaign that Mashable called the “least Apple campaign ever.”

In addition to the videos, animated by James Blagden ("Dock Ellis & the LSD No-No"), we created a series of posters that were featured in store and at an on-campus Jason Mraz concert for Apple employees. 

We also created a special Apple Watch challenge for Earth Day. Tim Cook Tweeted about it. 

Speaking of Tim, see if you can spot him in each of our videos!
