Steve Caplin takes us to the coldest place in the universe (only 250 miles away), gives us the chance to try out an Iron Man-style flying suit and tells us about a new scheme for renting phone batteries, how the French are banning smartphones at school and how the bubble car is making a return. He also discusses a chess board which moves the pieces automatically, a website for calculating quantities for groups big and small and what's wrong with ant emojis.
