Ick Can Stick! Make Milk Glue
What makes glue, paste or tape stick to things? Adhesives are used to stick things together. Wood, paper and many other materials have tiny cracks and holes in them. When we glue things together, sometimes the glue seeps into the tiny openings and hardens, making the materials stick together. Other times, the molecules on the surface of an object mix with the glue molecules, making the objects stick together.
