In this activity, learners separate the protein from milk and and use it to make their own glue. They will explore why there are so many different kinds of glue, and what uses different glues would have. Extensions include inventing new glues by using different ingredients and different ratios of those ingredients and testing their new glues against other more conventional glues. Part of the 21-activity guide published by OMSI, No Hassle Messy Science with a Wow.
