Last Sunday I decided to try out this angled Tic-Tac camera box I have been working on. I had been doing some more water tests, bud have not been able to find the leak I had in the first test. As of now I believe I had not put enough Vaseline on the lid.
Anyway I tried the Tic-Tac box out, and this is the resulting video:
I believe the water was clearer than last time I recorded submarine video.
As can be seen, using the air/water light refraction actually works and the angle I selected is useful.
