I’ve known about liquid filled lenses for some time Daniel, but ice lenses was something fun and novel – it’s only functioning as a lens while solid in a very temporary form. That said, liquid lenses I think have a powerful future with the right applications for legitimate professional and scientific work!

Your idea about the liquid lenses exists for many many years. There was even a liquid filled lens (for glasses) back then. It is more seriously under interest beginning the 1990s… See e.g. https://www.osapublishing.org/ao/abstract.cfm?uri=ao-32-22-4181

I was listening to your conversation about water proof. When I was in business a few watch companies advertised their watches were water proof. The ended up in court and lot their case. Now smart companies that claim to be “Water resistant” do so by stating just how “Water Resistant”. Like diving watches that are “water Resistant” to 30 or 50 meters. I know I have a Canon 7D that has gaskets to seal the camera but it isn’t water proof. I still protect my camera and lens too.
