Behind-the-scenes tours of local science, environment, and technology innovations.
In a dark lab at Lawrence Berkeley National Laboratory, engineers and mathematicians are developing new burners and studying different flames in hopes of better understanding the power of fire and how to make the most efficient flame possible.
Exploratorium Staff Scientist Julie Yu changes and manipulates the physical and chemical properties of plastic bottles by exposing them to heat. This is how plastic bags and bottles can be recycled and used over and over again.
The roadway across the Golden Gate Bridge rises and falls as much as 16 feet depending on the temperature. When the sun hits the bridge, the metal expands and the bridge cables stretch. As the fog rolls in, the cables contract and the bridge goes up. Curators from the Outdoor Exploratorium in San Francisco have set up a scope two miles away so you can see how the bridge is moving up or down depending on the weather.
Along with cable cars and seagulls, the Golden Gate Bridge foghorn is one of San Francisco's most iconic sounds. But did you know that if you hear that foghorn off in the distance, you can calculate how many miles you are from the bridge? Using the Speed of Sound exhibit at the Outdoor Exploratorium at Fort Mason, Shawn Lani shows us how sound perception is affected by distance.
