Gluey Geckos and Snow in Space

Dave Ansell

Why are Geckos feet so sticky? Can it snow on mars? Is it possible for someone to spontaneously combust? We answer these questions this week on Ask the Naked Scientists. We also find out why lemons float more than limes, reveal the correct terminology for the himalayas and how this region can control weather conditions on the rest of the planet, uncover what will happen when the sun stops burning and investigate how magnets work.
