We looked at the brilliant work of Arthur Fry. He accidentally invented the Post It note. His special glue meant that paper could be stuck down and lifted off without using any marks.
We made our own glue to see if we could use our own ingredients to stick two pieces of paper together, We used flour, cornflour, sugar, salt, liquid soap, detergent and water. We could use some of the ingredients or all of them. We were remarkably successful!
