Based in San Jose, the Tech Museum was designed to inspire people through documenting the world of science and technology through hands-on, interactive activities. If visitors can't make it down to their headquarters in California, this online series of exhibits is a nice surrogate for an in-person visit. The site always highlights three exhibits, and the most recent exhibits have included a "MPG Marathon" and "The Satellite Site". In the "Satellite Site", visitors can use graphics and interactive images to learn how satellites work, what they do, and also peer into the anatomy of these remarkable devices. In the "MPG Marathon", visitors can create their own energy-efficient hybrid car and then race it against two opponent cars to see how it performs in real-time. Finally, the site also contains eight archived exhibits that cover earthquakes, lasers, and a "robot zoo".
