Which drink freezes faster in frigid temps?

WASHINGTON — Unless you have an insulated mug you’ve probably noticed that your morning coffee hasn’t been staying as piping hot, with our recent frigid temperatures.

That got us to thinking in the Glass Enclosed Nerve Center — which morning drink would freeze most quickly if left outside?

Previous research has found that in certain conditions hot water can freeze faster than cold water, thanks to what’s been dubbed  the “Mpemba effect,” named after the Tanzanian high school student Erasto Mpemba, who first observed it, according to the LiveScience website.

This morning, we’ll simultaneously put mugs of chilled apple juice, hot black coffee, room temperature water, and cold 2-percent milk outside, and document what happens in the photo gallery.
