The viewing glasses are a hot commodity.
Local libraries are sold out, and so is the Chabot Space and Science Center.

Chabot is expecting around 1,000 people to view the partial eclipse atop the Oakland Hills.

Shipments at all of the locations have sold out or have been given away within hours this week.
Joseph Alvarez says the glasses are in such a high demand not even he knows where they are hidden within the library.
You'll want to show up early to the viewing parties at both Berkeley library and the Chabot Space and Science Center.
If you don't have the glasses, you can use your cell phone by flipping the camera like you're taking a selfie and turn your back to the sun.
Do not look directly into the sun without the protective glasses.
