A buddy of mine used to work on radio internet stuffs. He said water does all kinds of strange things to the signal and it's path. Transmitting over large bodies of water and in full sports stadiums can be problematic

It depends on the frequency, higher frequencies gets affected more by water and like.

Best one i have heard of was a wet dog acting as a very good wifi signal blocker.

I mean, if you really wanted to know about it - then you could have read a book about radio; wouldn't you?

Personally, I appreciate when science, math, history, etc. is added to the daily news.

It’s an enjoyable way to learn, and it provides everyone an opportunity to learn
