I assume you mean without it becoming a solid. Pull a vacuum on the liquid while cooling and you should be able to get it below the freezing point without it freezing.

Freezing point depression of a solution is a colligative property associated with the number of dissolved molecules. In other words, whatever the liquid, you can add a solute with a molecular weight that's comparatively much smaller than the molecules of the solvent in order to lower the liquid temperature below freezing and still keep it in a liquid state.

what liquid in particular?
you mean you want it to be still liquid, like supercooled? then you either filter it through the finest membrane filter you have or ultracentrifuge at high rpm (like 40000rpm for 20minutes should do???) - and put into some clean dustfree vial (like brand new one is the best idea) and cool down at the desired temperature. this way you remove all the crystalization centres. Way back in the lab i remember that stuff that was normally solid at +15 centigrade stayed liquid after being in the -80centigrade freezer for several weeks!

I was raised in a non-denominational church. I know what I believe about essential doctrines of the faith, and I have wrestled through many others. I think I know which denomination I would fit into if I were to join a "denominational" church. But for now I continue to attend the church I was raised in because of the strong Christian community I find there. Several years ago my sister became "denominational," so I began exploring her denomination in-depth. We agreed on so many things...but we also disagreed on certain doctrinal issues that were important to me, things which I believe to be Biblical, even though we are both sisters in Christ. So, though I may at some point join a church that is a denomination, I don't think I'll ever think of myself as Baptist, Methodist, or Lutheran. I am a Christian. I am a follower of Christ.

throw a chunk of dry ice in or add liquid nitrogen

non polar liquid can not cooled.because there is no attraction in molecules
