Bruce Grim has come up with a whole new series of objects for the next drop. Pictured at http://planet.state.ut.us/temp/test/LOW.JPG are the bowling ball we used before plus six white spheres (soon to be painted international orange or some other bright color). Four of the sphere are solid iron. The smallest is solid lead. And the third from the right is made of an acrylic substance that seems similar to the stuff the bowling ball is made from. Note that the acrylic ball is the same diameter as the much heavier iron ball to its side. Since they have the same surface area but very different masses it will be interesting to see if both hit the ground at the same time. The tentative plan is to drop all 7 at the same time, if we can figure a way to do it safely. Altitude, date, time and location TBD. Patrick
