Water turning into ice rapidly

[Anna O 2C]

I've seen videos where ice can be frozen to 0°C and remain in liquid form, but when you shake it, it immediately turns into slushy and freezes over. Does this have to do with the water graph we looked at today where there is a solid chunk of time/transition between solid and liquid? Where even though the water is the same temperature, it can be frozen or liquid in the same way that water can be both liquid and vapor at 100° C? How does this work?

I think this might have to do with how water bonds in a certain pattern when it forms ice (hexagon shapes)

this only works with distilled water, where the water molecules do not have something to bond around in their crystalline pattern, however when one shakes or disturbs the water, they molecules are jostled into place and freeze.
