Breman Universum

 I have always loved volcanoes and an exhibit on the natural science floor of Breman's museum provided further insight into certain mechanisms of a volcanoes. Sometimes, volcanoes produces something that resembles a smoke ring. As it turns out, these rings are not smoke, but water vapor and other gases. When pressure builds up in a volcanoes, these rings eventually get pushed up. The interactive exhibit at the museum demonstrated this by allowing users to evenly push down on the surface, propelling mist into the air to form a ring.
