Internationally acclaimed as the first hands-on science museum of its kind, the Exploratorium is home to more than 475 interactive exhibits, all of which create an otherworldly and awe-inspiring experience of everyday physical forces. More than half a million people visit the museum annually, and several hundred thousand more interact with exhibits sent abroad. The Exploratorium was awarded National Science Board 2011 Public Service Science Award for its continued good works in heightening awareness of the intersection of art and science, and it has trained more than 6,000 teachers in learning through hands-on interaction.
