This is a great party trick or anytime cool-down treat — by shaking up an unopened bottle of soda before cooling it for a few hours, you can make an instant slushie of any flavor you want.

Here's the process:

1. Get a room-temperature bottle or can of soda.

We attempted a homemade slushie, and were half successful. We think our problem was uneven cooling of the liquid in the bottle because it was lying on already frozen stuff. Hint: clear a small space on a shelf before attempting. Jennifer Welsh/Business Insider

2. Shake it up violently to increase the pressure. This pressure is what will keep the soda from freezing even when it's super-cooled.

3. Place the soda in the freezer on a shelf alone (it seems important that it doesn't lie on something already frozen, we tried this and the liquid cooled unevenly and started freezing on one side — still semi successful, see image, but not like the video) for two to three hours, then start quickly checking on it every 15 minutes.

In the video below the 500-milliliter sodas are chilled for 3 hours and 15 minutes. Our experiment froze quicker, but that could be because it was lying on already frozen stuff.

Be careful not to forget about the bottle, or you risk the liquid freezing and exploding the bottle. You are probably hitting the danger zone around about 4 hours, depending how cold your freezer is set.

4. Take out the soda bottle and open and close the cap quickly, before inverting the soda. The liquid will freeze into a carbonated slush.
