An awesome video has emerged from the UK of a science teacher freestyle rapping to his year eight class. <br /><br />The footage, filmed this week at a school in London, shows Christian Foley making up his lyrics on the spot, based on scientific words written on the white board by his students. <br /><br />He later wrote online: "This is genuinely my day job.<br /><br />"Ever wondered what a rap teacher actually does at school?" <br /><br />"As part of Science Week, my Year Eights put seventeen scientific terms on the board, and asked me to freestyle them all in order," he continued. <br /><br />"From Pollen Grains to Germanium - Challenge Accepted."
