In the build-up to the Christmas Lectures in 2012, the Royal Institution published a new video for every day of advent revealing the elements that really excite and inspire people. In this short film, children's presenters Richard McCourt and Dominic Wood (Dick and Dom) explain why they are big fans of nitrogen. Not only does nitrogen form 79% of the air they breathe, but it is also needed to make amino acids. Amino acids are needed to make proteins and without proteins, they say, there would be no “bogies”.
