Details:
John Stetson suggested using a vegetable steamer for safely projecting the Great American Eclipse. While that will certainly produce lots of bright images of the Sun, the holes might be a bit big for clarity. Maybe try a water biscuit instead: with smaller holes, you'll see more detail of the bright crescent Sun. [I know that a 'biscuit' in the US is what I would call a scone, but I don't know what you would call our biscuit!]
Smaller holes will give a fainter image, but it will be sharper.
