The voltage went down on both cells due to you making them cold, so if cold makes the cells go down than heating them makes them go up just like how you shown. When you heated the water battery with a touch you supplied a instant heat source thus the voltage went up quickly. The ZnO cell you did not put a torch on it so it heated up slowly due to the surrounding air being hotter than it so the voltage went up slowly. Just because you froze it doesn’t mean it will stay frozen, as soon as you remove the cooling it starts to heat back up because it wants to be at the temperature that surrounds it.
The freezer allows it to cool slower and more evenly. In the video you cooled the Water based cell for longer than the ZnO cell, so it didn’t seem fair. Allowing them to cool in the same environment for the same amount of time will really help out a lot. You should have nothing to fear, its a simple test. It doesn’t matter how cold you freezer gets as long as it below 32 degrees F so it freezes water.
If you could post the list of stuff needed to replicate your cell I would try to make it. thanks.
