Snow are able to grow to hundreds of micrometers or millimeters in size at the expense of the water droplets by the Wegener–Bergeron–Findeisen process. The corresponding depletion of water vapor causes the ice crystals to grow at the droplets' expense. These large crystals are an efficient source of precipitation, since they fall through the atmosphere due to their mass, and may collide and stick together in clusters, or aggregates. These aggregates are snowflakes, and are usually the type of ice particle that falls to the ground. Although the ice is clear, scattering of light by the crystal facets and hollows/imperfections mean
Frozen custard product leaves the barrel minimizes the amount of air in the product but more importantly ensures that the ice crystals formed are very small. Frozen custard Frozen custard is a cold dessert similar to ice cream, but made with eggs in addition to cream and sugar. It is usually kept at a warmer temperature compared to ice cream, and typically has a denser consistency. Egg yolks have been integrated into ice creams since at least the 1690s, though there are several notable invention stories that are associated with modern commercializations of this practice. One early commercialization of frozen custard was
