We saw this unusual looking swing at the fun fayre few weeks back. It has 2 tiny seat on each side and swing from side to side. It was decorated with beautiful paintwork and it has a rope on each side so when the child pulls it, it will swing to that direction. So you could imagine that 2 kids sitting opposite of each other pulling the rope in turn and this vintage swing will moves.
BUT, it comes with a big price tag. 1.5 GBP per rides.... and my son only sat for barely 5 minutes?! oh, dear.
