The green, red and blue dyes in plastic milk bottle tops used in many countries are a real problem, says material scientist Sujata Kundu. The colours are hard to separate from the main plastic polymer and, as green tops are the most popular in the UK, the recycled plastic tends to have an un-appetizing green tinge. So Sujata wants us either to switch to colourless bottle tops, or, better still, change to an exciting colour, such as purple, so that recycled plastics become widely accepted.

Writer Shumon Basar wants to create a personal ‘time-bank’. It would record exactly how much of your day has been lost when your computer freezes or there’s no phone signal. Then, just before sleep, you would strap your phone onto your head, turning it into a personal virtual reality environment. Ping! Suddenly you are on an idyllic island beach. In real terms, you’ll be there for exactly the time you lost during the day. In neural terms, time will stretch by ten times. One lost, frustrating minute from the day will feel like many rejuvenating minutes on a better side of the planet.
