Fanatic about leaving a small carbon footprint? Two Scottish scientists may have made your day. They’ve come up with a way to make fly rods with carrots. “At the moment, the company can make materials which are around 80 per cent carrot, with carbon fibre making up the remainder. The new ‘Just Cast’ rods are around 50 per cent carrot – each made with around 2kg of the vegetables.” Our only advice is that you not take any streamside naps with rabbits in the vicinity.
