Introduction

Do you want to know how to make instant ice in 5 seconds? Have you ever put a soda bottle or frozen water for some time to make it cold? When you want to drink it, it is still liquid, but the liquid turns into slush when you twist the cap. This is an example of how extremely cooled liquids refuse to freeze even at a temperature below their normal freezing point. So, do you want to make an instant ice tower? The ice experiment for kids is very easy and requires a significantly less supply of materials to do so. However, the impact of this science experiment is huge. When you pour the liquid water, it will magically turn into ice in front of your eyes. 

However, it might not happen at the first attempt. All you need to do is understand and be patient because it is the right measurement of ice, time, water, and salt. You can make an instant ice experiment video, every time you conduct the experiment and learn from your failures. The experiment is cool but does remember not to use glass bottles.  

Materials Required

  • Bottled Water
  • Ceramic, steel or Glass Bowl
  • Shallow metal cookie sheet or plastic tray
  • Ice cubes
  • Freezer
  • Rock Salt 
  • Thermometer

Procedure

  • Fill the ceramic, steel, or glass bowl with ice cubes.
  • Shove two bottles of plastic that are refrigerated, deeply into the ice. Closely keep them in the bowl’s center and ensure that they are buried and surrounded by as much ice as possible.
  • Spread some amount of rock salt on the ice’s surface.
  • For doing the ice experiment for kids accurately, put inside the thermometer in the ice and between two bottles. Keep monitoring the temperature. You will see that the temperature will fall in the next thirty minutes. You can add more ice and rock salt to the bowl to ensure that the bottles are correctly inserted. Keep a watch on the thermometer.
  • You will notice that the bowl’s temperature will drop to 17 degrees Fahrenheit, i.e. -8 degrees Celsius. Make sure that water does not get colder, and else it will freeze prematurely. Whenever you are performing science activities for kids always be particular to details and supervision.
  • After the water’s coolness has maintained its temperature for approximately ten minutes, remove the bowl’s bottle. Sharply bang the bottle against the surface. You will see the immediate formation of an ice crystal at the bottle’s top. The ice will start forming downward toward the liquid.
  • In this ice experiment for kids, you can also do it by carefully removing the other bottle and twisting the cap open. You will see the same quick freezing from the bottle’s top to down.
  • This instant ice experiment with salt is quite cool and exciting.

How It Works

In this ice experiment for kids, you used ice and rock salt to bring down the water temperature below its freezing point. This concept is known as “freezing point depression”. The cod saltwater can cool the other soda and water samples to check out which supercools are below their freezing point. By doing so, you will also find out which samples freeze at their normal freezing points.

From this ice experiment for kids, we understand that as water freezes, water molecules start forming a crystalline structure because they come closer in an orderly way. Thus, water molecules have the same energy as ice molecules. To change their liquid state to solid state water molecules must lose the heat energy. Super cool water will freeze when you open it, and it will also warm the remaining water. The heating allows only ten to twenty percent of water to cool, allowing for the formation of slush instead of solid ice. This is because heat flows slowly in water, and ice crystals are formed quickly.

When the water reaches the freezing point, the ice crystals start collecting in the water. To understand better about this science ice experiment for kids to think about snowflakes. The crystals in the snowflakes require something to grow on. Thus, they use water’s impurities or around the surface of the bottle to grow. However, when you use real pure water, the outcome is different to produce supercool water. When you add impurity in the super cool water, the process of crystallization speeds up. The water changes to solid-state instantly without any semi-solid ice in it. This process is known as “snap freezing”. This is one of the best science activities for kids to perform and learn.

Conclusion

The ice experiments for kids can be done with soda pop or sparkling water. Many additives with carbon dioxide are added to produce soda water. The additives are known as solutes and when these are mixed in water, the water from the standard freezing point. This means soda needs to reach a much higher temperature to freeze as compared to water. However, this science experiment for kids is exciting to perform.
