Exhibitor: Phi Sigma Rho Location: Grehan / Second Floor Room 202 - K About the Exhibit Learn to make slime with Phi Sigma Rho! We'll be using glue and borax to create slime. When the glue's polymer molecules mix with the borax activator, they link together and turn the liquid into a stretchy, squishy material. Come make your own slime and learn how it works!
