Use a net with not too large holes, yet not too small holes.
Hence, the small beefs with fall out, and the large ones will remain in the sieve/net.
The answer is disturbance; energy.
Waves deliver a method of transporting energy without
transporting matter. Undertaking of the particles are similar to the motion of
the energy. Sound waves touching over the air is an instance
of this kind of wave.
The vibration is thermal energy ("heat" energy which every object possesses).
The second one is kinetic energy ("motion" energy of a massive object)
