The freezing point decreases slightly with increased pressure. See the phase graph at the related link.
I do remember seeing a science fair project, where the student attached a weight to a fishing line or dental floss. Then he put it over a piece of ice. The weight, distributed over the small surface area of the string caused high pressure on the ice, which lowered the freezing point enough that the ice melted. As soon as the ice melted, the weight would pull the string down through the water, so then the water no longer had the high pressure on it, and it would freeze again. After several minutes, he picked it up, and the string ran right through the center of the ice cube.

Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Atmospheric pressure and the presence and concentrations of solutes affect the freezing point.
How does pressure affect freezing?
Increasing pressure will give a lower freezing point. So if you wish to keep ice cold longer, increase pressure on the ice.
How does changing the concentration of a solution affect the kf?
Increasing the concentration of a solute the freezing point depression is increased.
Would vinegar affect the freezing point?
Vinegar will not affect the freezing point of vinegar.
Is it true that water would never freeze at -4C?
No, pressure affects the freezing point of substances. When you increase the presure, you lower the freezing point. So if you kept water at -4C then increased the pressure enough, the water would start to freeze
What affects freezing point?
The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.
Why is the curve for the freezing point of solvent different from the freezing point of solution?
it is increased with the increasing density
Can the freezing point be lower than its boiling point in a constant pressure?
At a constant pressure, the freezing point is always going to be lower than the boiling point.
Is freezing boiling or melting most affected by pressure?
Boiling point is most affected by pressure. Note that freezing point and melting point are in fact the same.
How does the number of moles affect the freezing point?
Higher the concentration of the solute, lower is the freezing point.
Will NaCl's affect the freezing point of a solution make the freezing point increase?
The freezing point of water solutions containing sodium chloride is lower.
Does salinity affect the boiling point of water?
as the salinity of water increased the bioling point increased and the denisty as well
