- Make a pinhole viewer: Cut a 1-2-inch hole in a piece of card, stick aluminum foil over it and use a pin to poke a hole in the foil. Place a second piece of card on the ground and hold your pinhole viewer above to project the sun’s image onto it.
- Use a colander: Hold it up to the sun and look at its shadow for a natural pinhole viewer.
- Look between the leaves: The shadow cast by the gaps between foliage can also act as natural pinhole projector.
- Use a solar telescope: You can check with your local observatory if they’re running an eclipse viewing event. It’s not safe to use a regular telescope.
- Watch the livestream: The Royal Observatory will be livestreaming the solar eclipse.
