This is my new mug - I always had a fond love of the Periodic Table as a child. As a master of my Chemistry class, I actually used to be able to quote every element from the table on request.  My lab teacher in high school sported island hair and a yellow jeep. I’ll never forget the day that after heavy explanation not to mix a chemical (i think it was either a chloride or fluoride) with water as it would become an extremely corrosive; he then proceeded to clean up the mess he had made with a damp sponge. This quickly disintegrated and then he burnt his skin. All highly amusing for a class of 16 year olds!
