The currency acts as a water sealant, creating a system of balanced upward and downward forces. The water remains at rest until the demonstrator yanks out the dollar bill. Background information and reference material on Newton's First law are included. Phun Physics is a collection of physics demonstrations which introduce basic physics topics and can be varied for presentation to grades 3-12. <b>Se Related Items</b> for a link to the full collection.
