The lakes near volcanoes
Once, I was vacationing with a group of friends; we went one afternoon to a volcanic area with lakes around it. These types of sites are usually hot. That is why we thought it was a good idea to bathe in the hot lakes.
What no one ever told us, and what we found out later, was that the lake could explode. Yes, this is how you read it. If the volcano had been pushing carbon dioxide to the lake, we could have exploded like a soda can after being shaken. Don’t do this at home and never go near lakes near volcanoes.
