CAN you help identify the mysterious substance that has turned a puddle at UWS luminous green? 

One passer by spotted the water on the river path at the front of the university campus in Ayr on Friday afternoon.

Iona McMillan got in touch with us and sent us this picture. She said: "Do you know what could have caused this in the puddles beside the river at the university? I just walked past it on my way to work. It's luminous green."

It has been suggested that there may have been 'muck up' celebrations from students who have finished exams or are graduating but nothing has been confirmed.

Families and pet owners are also advised to keep children and pets away from the liquid until there has been named.
