In general, household aluminum foil is an inexpensive and effective method for handling meteorites. You can cover the end of the magnet with tape before dragging it across the ground if you use it. The friction between the meteoroid and the atmosphere creates an extremely high temperature and melts most parts of the meteoroid. You can also search in "strewn fields," or zones where meteorites from a single space rock were dispersed as it broke up during atmospheric entry. Small pieces of rock or dust that fall into Earths atmosphere from space are referred to as shooting stars.
