Can you solve the BOWL RIDDLE? ft. Kurt Hugo Schneider Part 1/3

(1) The bucket riddle 
I initially thought about how 25 degrees fahrenheit is below freezing but then thought about how long was the bucket left at that temperature, how heavy the king is and from what height were they dropped. My thoughts were on air temp rather than the temp of the water, and I was wondering how long a sufficiently thick surface of ice would take to form to prevent the wooden king from falling through. A long round-a-bout way of saying it would at least hit the bottom of the 25 degrees celsius bucket first, if it hit the fahrenheit at all, which it wouldn't as all water at -3.888C (this was Googled) would be solid ice.

(2) The clock puzzle
24 hr clock - 00.00 
12 hr clock - 01.10 or 11.11 if they're like one of mine where it's displayed 1.10
Secondary thoughts; 00.00 to 00.00 is 24 hours.
Tertiary thoughts; Previous thoughts are somewhat rubbish, it's between 2 separate times, 24hr, 00.00 to 01.10 is 1 hour 10 minutes. Now not typed but running through other times. 
23.32 to 00.00 is only 23 minutes. 
12hr, 12.21 to 01.10 is 49 minutes if the first zero of 01.10 is counted. If not, 10.01 to 11.11 is 1 hour 10 minutes, same from 11.11 to 12.21.
So, 24hr; 23 minutes between 23.32 and 00.00
12hr (with 4 digits for all hours); 49 minutes between 12.21 and 01.10
12hr (without 4 digits for all hours); 1 hour 10 minutes between 11.11 and 12.21

I thought it required 4 digits. So a palindrome only requires all values to be reversed, 1.01, the last 1 becomes the first and the first the last with the 0 staying put. 

(3) The bowl riddle
My first thought was a whirlpool, stir the water fast enough so that it all wants to flow to the outside of the bowl enabling the 'ball' to 'fall' or be drawn down into the centre of the bowl.
Second thought was if the sensor in the 'ball' has metallic parts a large enough magnet could possibly generate enough force to be at the bottom but as the bowl is metallic it would more likely just be drawn to the edge of the bowl as the resistance of the water would be much higher even if it could be kept perfectly central to even out magnetic attractive forces to the edge of the bowl, however if it was attracted to the side then moved down to the bottom with the magnet outside and the 'ball' inside.
