But scientists have found ways to manipulate the freezing process of water and the production of these nuclei to create snow artificially. Chemistry - Atoms And Bonding - Learning Points. Snowflakes need ice-forming nuclei, such as dust, bacteria and pollen grains. Snowflakes can be created from supercooled water, which remains liquid below zero degrees Celsius. Supercooled water immediately crystallises when it comes into contact with foreign nuclei. Indoor ski slopes use supercooled water to create fake snow. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
