On this weeks snow-bound Naked Scientists, we're taking on your science questions! We discover the caterpillar that tricks it's ant hosts into treating it like royalty, find out why fish get lost in acidic seas and why the gravitational pull of tonnes of ice may lead to greater sea level rise than predicted. Plus, we find out what happens to salt after it's spread on roads to avoid ice, what processes make the sea salty and how scientists weight the moon. In Kitchen Science, it's 'on your marks' for a microwave race - will water boil before ice melts?
