How to watch safely
Never look at the Sun without certified solar viewing glasses that meet the ISO 12312-2 standard. Sunglasses, smoked glass and exposed film are not safe. Check the glasses for scratches or holes before you use them, and supervise children.
Never point binoculars, a telescope or a camera at the Sun unless a certified solar filter covers the front of the optics. Don’t use eclipse glasses to look through unfiltered optics: the concentrated sunlight will burn through them and into your eye.
A pinhole projector is a safe, simple alternative: let sunlight through a small hole in card onto a surface behind it and watch the projected crescent. Even at maximum, part of the Sun stays uncovered, so protection is needed for the whole eclipse.
