Science geeks unite! According to the website, this facility “serves as a laboratory for controlled scientific studies, an arena for scientific discovery and discussion, and a far-reaching provider of public education.” The Under the Glass tour leads you along a trail where you explore the rainforest, ocean, coastal fog desert and wander through the underground technosphere.
