Bang!: How is the Energy of Seismic P-Waves Transmitted Through
the Earth? How is the energy of seismic P-waves transmitted
through the earth? - Masking tape - 5 marbles - Cut 5 pieces of
string, each 12 inches (30 cm) long. - Tape one piece of string
to each of the marbles. - Tape the free end of each string to
the edge of a table. Adjust the position and length of the
strings so that the marbles are the same height and touching
each other. - Pull one of the end marbles to the side, and then
release it. - Observe any movement of the marbles. The marble
swings down, striking the closest marble in its path, and stops
moving. The marble on the opposite end swings outward, and
strikes its closest neighboring marble when it swings back into
its original position. The cycle of the end marbles swinging
back and forth continues for a few seconds. Raising the end
marble gives it energy, which is transferred to the marble it
strikes. This energy is passed from one marble to the next, as
each marble pushes against the
