Four-year-old Henry Himmelberger, of Snoqualmie, holds a Madagascar hissing cockroach during a Science on Wheels enrichment class Friday, Jan. 29, at Encompass. More than a dozen preschoolers attended the class, taught by the Pacific Science Center, and all got to hold one or two cockroaches, neither of which hissed, which is a sign of contentment.
