Liquid sponges are counter-intuitive in the extreme, yet Katharine Sanderson manages to describe what is going on at the molecular level in these new materials in a completely comprehensible way. She achieves this by using analogies with everyday objects that we all understand – doughnuts, pasta, dinner plates. As a one-time secondary school chemistry teacher, I am full of admiration(11 March, p 43).
