Its called the liedenfrost effect(see video below), the noise is when the effect wore off and the nickle began to cool rapidly.

It seems as if the nickel being so hot made a field of heat around the water and the water cooling it over time at the rate it was cooling was "pricing" layers of heat eventually hitting the surface and rapid cooling causing vapor heat to expunge profusely ending. The ping noise I cannot guess.

mythbusters actually did a segment about this effect and ended up dipping their hands into molten metal.

Same thing happens on a nickel plated grill.

the water around the hot ball is vaporizing almost instantly, thus creating a vapor shield around the ball. What i would like to see the the temperature change of the water.

Ah no. I got it. It is being insulated by its steam. The steam is trying to float up but is instantly turned back into liquid so the steam only exists around the ball. The chirping is still the sound of water touching the ball and instantly turning to steam. As the temperature of the water and ball get closer the steam is eventually able to reach the top of the water by bubble without being cooled back into water. The bubble around the ball is then broken and more contact to cooler water makes all the noise and rapidly cools and the steam breaks away.

Well I presume the area of gas you can see around the ball when it goes in is the leidenfrost effect in action but how that makes for the really cool sounds I`m not sure...pressure waves as it cools rapidly?

It looks like it is being insulated by the steam it is creating and each chirp is water breaking through the steam wall and touching the ball. I just don`t understand why the steam isn`t floating up and away from the ball.

the water is vaporizing faster than it takes to touch the metal.
