Is Elmer's glue heavier than water?

Elmer's glue is generally denser than water, which means it is heavier. The density of most white school glues, like Elmer's, is around 1.1 to 1.2 grams per cubic centimeter, while water has a density of 1 gram per cubic centimeter. Therefore, if you compare equal volumes, Elmer's glue will sink in water.
