Solar Chocolate

This was the coolest candy experiment I've ever done--or maybe the hottest?

Upon realizing (1:30 am last Saturday morning) that the upcoming solar eclipse was a rare annular eclipse that we'd actually be able to see from the southern US, we packed up and started driving south that very day. 26 hours later (we arrived at a Utah mountaintop in time to watch the celestial spectacle as the moon began to cover the sun. To watch the eclipse, we could use a welding face mask, a telescope flipped backwards to project the eclipse onto a white poster, or a pinhole viewer, in which the light goes through a small hole to project the sun's shape.

Here's the solar eclipse as seen through the backwards telescope, with the moon covering most of the sun.


And here's my pinhole solar eclipse viewer.
See that crescent shape in the middle of the shadow? That's the shape of the eclipse.
