Albert was off to a school sustainable expo to check out the displays. The hands-on stuff was brilliant. The solar cooker and a fantastic model of the water cycle in an urban area. He could watch what happens when he washes the car, where the water goes- showing the importance of keeping storm water drains clean as it eventually goes out to sea. The water was dyed to show easily the track of the water. That's where Enjo- fibre based cleaning without detergents is so good.
