Try it with a candle and a roll of paper towels. :)
How about a flashlight and an onion

My results were somewhat inconclusive at first. You could see the light from the flashlight lighting up the very edge of the onion with sharp, definitive light, but the part of the onion that was closer to me was comparatively dark. There were rays of light going directly into my eyes from the flashlight, which reminded me of the rays of light from the sunset that come visibly towards you over the water. Unfortunately they made it very hard to see!
I decided to try it from another angle as it seems impossible to objectively tell if the onion was actually being lit at the top or not. From a side view if you hold the onion level with the edge of a table, you can slowly move the flashlight up and down in height to see where the sun's rays would be illuminating the earth. Using this method, the onion was lit up even when the flashlight was well below it! I am sure this method is not perfect, but I believe it to be more accurate than the paper towels with a candle. The onion is round, instead of cylindrical (and I don't have a candle, but figured the sun irl to be way more powerful than any flashlight anyways

)
Actually out of fairness, I ended up trying it with a lighter flame as well. This was a lot less bright in general and didn't light up the onion very well at all, but given this same side view it was basically just a dimmer, less defined version of what the flashlight showed.
I would post pics of the flashlight version, but unfortunately my flashlight and my camera are one and the same

However, while doing this experiment, I did notice another example of how light could behave in the way that you see during sunsets on RE.
The following pictures show a recessed light fixture. The lightbulb is higher up than the fixture and ceiling that contain it. Despite this, it illuminates the ceiling clearly. Now, better than this, you can see that this ceiling is tiered. A little over 1ft past the light fixture, the ceiling rises up by about 1ft. (This section of the wall is painted green, while the ceiling is white)
You can see in the photos that the higher part of the ceiling is
not illuminated in the same way as the part by the light fixture. What this demonstrates (unless I am misinterpreting here) is that the light can bend around slightly greater than 90⁰ corners. It does have limits though, and you can see it reaches the limit when trying to illuminate the higher portion of the ceiling.
Let me know what you think of this :)
