The Institute of Water Research returned to the Michigan State University Science Festival this year, highlighting the importance of groundwater through an interactive “Edible Ice Cream Aquifers” session. Roughly 100 participants made their own “aquifer” out of ice cream, cookies and gummies and simulated pumping with a straw. In addition to creating ice cream aquifers, Ruth Kline-Robach presented a groundwater model, demonstrating how pollution can move through a groundwater system.
