"Explosive" Physics.
Kienzynski, Mark J.
Hoosier Science Teacher, v24 n1 p30-32 Sep 1998
Describes a physics demonstration in which two-liter plastic bottles can be used to show how force relates to pressure and area. Identical drinking straws are launched out of similar plastic bottles with different-sized openings. This demonstration proves qualitatively that pressure is inversely proportional to the area exposed to an object when a force is exerted. (PVD)
