How lava lamp work?

Answer 1

I just had the good luck of explaining this to some folks in a Senior citizen home. most were ( All ears). The basic principle is there are two fluids having different densities or specific gravities. the heat to nurture the para-reaction ( which never goes all the way) comes from a standard light bulb. the bubbles rise- fall expand and contract. in part it is based on two conductive fluids that are never quite in balance and thus it is can be called a Hypostatic Union- do not confuse with the theological use of this term for God-Man state! that"s how it works .
