An experiment in refraction

Pink flamingo swizzle stick refraction

One well  known effect of the refraction of light as it passes from air to water is that a stick partially submerged in  water will appear to bend where it enters the water. Water is boring, and I don’t have any sticks, but in the interests of science I experimented to discover how much a pink flamingo swizzle stick will appear to bend when partially submerged in sparkling wine compared to in a martini. The results are quite different, which makes me wonder if the shape of the glass has anything to do with the effect?

The stick does appear to bend slightly as it enters the bubbly, but the effect is not dramatic. Interestingly, you can also see how the black line that swirls around the glass appears to 'jump' where it passes behind the wine-air boundary.

Now, here we have a dramatic bending effect! Look at that sharp zig zag shape in the stem of the swizzle stick. Also some very cool reflections happening inside the glass.

 

Oh, the things I do in the name of science!

Three by Three

The current theme for Weekly Photo Challenge is Threes, i.e., telling a story in three photos. I couldn’t decide which set of threes to go for, so have opted for three threes. Too much of a good thing?
