Machacek Library's Saturday STEM Lab on Dec. 5 (10:30–11:30 a.m.) centers on elephant toothpaste, the foamy reaction that grows out of its bottle and gives off heat. Kids ages 5 to 10 watch the mixture bubble over and talk through why it happens, getting a simple introduction to chemical reactions. A weekend time slot makes this one easier for working families.
