Neon is normally odorless and colorless, reacting with no one, not even itself. Abundant in the universe, uncommon on Earth, it drifts aloof from any bond. When isolated by Sir William Ramsay and Morris Travers inside a vacuum tube in 1898, the noble gas betrayed its excitement in brilliant red. That excitement, glowing within Georges Claude’s ingeniously curved lamps since 1923, has captured our imaginations ever since. Recorded live at the Exploratorium 2015.
Earth, water, air, fire: our world is ruled by oxygen, the third most abundant element in the universe. Originating inside of stars, oxygen is scarce on planets outside our own. It comprises roughly half the mass of Earth’s crust and a fifth of its atmosphere. Nonmetallic and highly reactive, oxygen is key to combustion and corrosion, and forms stable bonds with almost every element, notably hydrogen (H2O) and itself. Recorded live at the Exploratorium in 2015.
Earth’s oxygen is produced in equal measure by terrestrial vegetation and microscopic life in the sea. Explore the profound influence of phytoplankton on the atmosphere with Exploratorium scientist Jennifer Frazier, and learn how their populations are changing along with our climate. Investigate oxygen’s physical properties and follow the history of its discovery, as well as its more breathtaking applications. Follow the trail of this intriguing element through ceramics, cleaning agents, fireworks, nuclear reactors, and nanotubes. Get a primer on quantum mechanics, play with slime, and see live flameworking with Russell Taylor of Public Glass. Behold beryllium, an exceptionally light, strong metal that is both prized and poisonous. Found in minerals such as emeralds and other forms of beryl, beryllium is highly conductive to heat and electricity, nonmagnetic, capable of great elasticity, and impervious to a wide range of temperatures, making it a favored material for aerospace projects such as space shuttles and satellites.
In this video you will discover the element’s ancient and atomic histories with host Ron Hipschman! How do brewers turn a handful of simple ingredients into the frothy, delicious beverage we call beer? Patrick Horn and Bryan Hermannsson from San Francisco’s Pacific Brewing Lab take us inside their testing facility and show us how a new beer is born. Join Dr. Russell Schnell, the director of the Global Monitoring Division of the National Oceanic and Atmospheric Administration (NOAA), as he talks about what it takes to monitor climate change. Join us for a preview of Oaxacan artisans that will be visiting the Exploratorium this summer as part of Colorfest! Made by the Exploratorium's Teacher Institute, this "machinima"--a film made entirely in a virtual world, highlights the exhibits and recent events in Second Life on the Exploratorium Island and 'Sploland sims. This week's secret ingredient was triangles! Cheer on the competitors in this zany science cook-off. Teachers compete before a live audience at the Exploratorium for the revered title, "Iron Science Teacher."
