Today’s experiment may be something you’ve seen on social media, we’ll be freezing a bottle of water and growing ice crystals instantly.
We’ll be working with supercooled water, which is water that’s cooled below the freezing point but remains in liquid form. The process we’re demonstrating today is known as nucleation. Nucleation describes the process where ice crystals begin to form around a point known as a nucleus. Once the ice crystals form around the nucleus, they’ll continue to grow throughout the liquid.
We’ll need purified water because it’s free from sediments and impurities. If we were using tap water or mineral water, the minerals/sediments in the water would act as nuclei and freezing would begin too soon.
To get started, place two bottles of water in the freezer and set a timer for 2 hours and 15 minutes. It’s important that these bottles are undisturbed throughout the entire 2 hours and 15 minutes. If the bottles are jostled or the freezer temperature changes too rapidly, the nucleation process could begin before we want it to.
After the timer goes off…gently remove one of the bottles from the freezer. If everything has gone according to plan, the water should still be in its liquid form.
Now slam the bottle on the counter. The entire bottle of supercooled water should freeze within seconds. This happens because the jarring motion forces a few of the water molecules to line up into a crystal lattice structure that acts as a nucleus for the rest of the crystals to grow off of. Super cool!
Take your second bottle of supercooled water out of the freezer. Pour the water over your ice cubes and watch as the water instantly freezes and creates an icy stalagmite.
That’s because the ice cubes are made up of ice crystals so when the supercooled water touches them, it instantly freezes.

Several actions can trigger the nucelation process, including something as small as a piece of dust that the molecules can adhere to, or a rough spot on the surface of the bottle. Another trigger can be the shock wave generated by hitting a bottle just out of the freezer against a table. Stay Connected
The process water undergoes to become crystals, or ice, is called nucleation. Nucelation occurs when molecules in the water clump together, forming a crystal-like nucleus. Once formed, other molecules can latch on to the nucleus.
Watch this! A video shows water in a bottle freezing instantly just by hitting it on a surface.
It is because the water in the bottle is supercooled. A supercooled liquid is one in which the temperature is below its normal freezing point, but the liquid has not solidified. This is because the liquid needs something to initiate the freezing process – something to encourage a number of liquid molecules to get together in a regular pattern, which they do in a crystal rather than moving freely in a liquid.
How To INSTANTLY Freeze Water On Impact!
Why does water in a bottle freeze instantly?
KALAMAZOO, Mich. — Watch this! A video shows water in a bottle freezing instantly just by hitting it on a surface. Why does this happen? It is because the water in the bottle is supercooled. A supercooled liquid is one in which the temperature is below its normal freezing point, but the liquid has not solidified.
Can you freeze water bottles?
Getting your water bottles to freeze instantly might take a few tries. If your water bottles don’t freeze instantly, try adding more salt to your ice water mixture, or cool the water bottles in the mixture for a longer period. Never use glass bottles when freezing bottled water.
How do you freeze a super cooled water bottle?
To instantly freeze a super-cooled water bottle, hold it by the neck and tap it on the bottom with your other hand. If a snowflake or ice crystal forms, it should grow until the entire bottle is frozen. This may take just a few seconds to a minute, depending on how cold the water is.
Why does water freeze so fast?
Ice crystals then form throughout the liquid, turning our water into solid ice over time. Pure water has no impurities, so without a nucleus to kickstart the freezing process, the water becomes supercooled. This allows the water to freeze faster when exposed to an external nucleus, making the magic of “instant” ice possible.
