Need Ideas for Fun, Cheap Projects for Families to Do on Museum Visits
I work at a science center (www.lsc.org) and need a variety of projects guests can do that are CHEAP, fun and provide a take-home object. I love the water bottle speakers, but they involve expensive parts. Ditto for the jar that glows at night. Any thoughts about a project for all ages that won't cost more than about $2-3 per person using mostly recycled parts? We get about 1,500 people a day, so any dontaed parts would also be appreciated.
