nono dont get the wrong idea
gravitional potential energy is converted to kinetic energy, which accelerates the liquid down. after it hits the spoon, energy is lost as heat in friction (a tiny amount) thus the liquid doesnt move alot. it also doesnt move alot because its quite dense.
if u put a denser liquid onto a less dense liquid, no matter how lightly u put, the denser liquid will sink down, (think of an iron ball on cotton wool, no amtter how lightly u place it the iron ball will crush the cotton wool)
most liquids are free-flowing and have no rigid arrangement of particles. hence gravity doesnt change the liquid in any way.
the spoon only absorbs the kinetic energy released by the liquid.
yes the 2 liquids dont mix at all. thats better known as immiscible liquids.
the spoon slows down the liquid by absorbing the kinetic energy away and since the spoon is lower, the liquid now has less gravitional energy, and also has a shorter distance to fall from.
the spoon functions as an impact cushion
(think of how people are rescued from buildings. firemen often put out a parachute because if the people just jump down, they may be killed from the impact. with the cushion, their landing is generally safe and they are safely lowered down to the ground.)
