This cold weather clear ice trick takes your cocktails to a new level

Impress your guests with perfectly clear ice made by Arctic temperatures

It’s cold out there! But why not use your problem to your advantage?

This clear ice experiment takes advantage of extreme cold temperatures to help you take your hosting game to a whole new level (especially if you have limited freezer space). 

All you need is a cooler, some water, and some extreme cold.

But here’s the catch: once you put the cooler outside, you need to take the lid off.

This method takes advantage of the principle of directional freezing.

When you freeze ice cubes in your plastic tray, the water freezes from all directions. This pushes air bubbles and impurities in the water towards the centre of the cube, which turns cloudy.

Because the cooler is insulated on every other side, the water will freeze from the top down, pushing that cloudiness to the bottom of the cooler.

Of course, the exact time you’ll need to leave the water in the cold will vary depending on the size of your cooler and the temperatures outside. But generally speaking, once you can see that a substantial layer of ice has formed, bring the cooler back inside and leave it flipped over in your sink or bathtub until your clear cocktail ice block slides out.

From there, simply take a sturdy knife to the block to cut away your crystal clear cryospheric creation, courtesy the extreme cold.
