A lot of potential energy is being released and converted into kinetic energy. Dominoes and marbles, sure. But every time a coiled spring's energy is released, that adds energy to the momentum - or, more precisely, it converts stored non-kinetic energy into momentum, aka kinetic energy. 0:59 shows gravity assisting the sieve's slide down, 1:06 shows a weighted lever triggering the coiled mousetrap spring. The guitar at 1:30 is powered by a weight sliding down (right of screen).
