Great Lakes Science Center will be closed on Easter Sunday but the facility has plans to celebrate the holiday with Eggsperiment!, a family friendly event that takes place from 10 a.m. to 5 p.m. today and tomorrow. Designed to celebrate the “amazing structure of the egg,” the event will let patrons see if it's really possible to stand on a carton of eggs without cracking any, why eggs are, well, egg-shaped, whether or not you can create a contraption that will safely deliver an egg from an 80-foot drop and whether eggs can only balance upright during an equinox. Guests can also delve into the chemistry of candy, become structural engineers to build bridges for bunnies and discover how force and angles all play a role in elastic energy. All activities are free with paid admission to Great Lakes Science Center. Plus, for the weekend, members will receive an extra 5 percent off purchases in the Science Store (15 percent total discount). (Niesel)
