(ELI5) Why does water when put in the freezer turns to ice, but never snow, while when the weather is really cold, the rain turns to sleet sometimes, but can aslo turn to snow?

It's because in the freezer there are no small droplets like in a cloud. If the small droplet freezes, the water crystalizes and becomes a snowflake. But in the freezer the whole container of water freezes and the small crystals connect together, becoming ice. If you open and close  the freezer often, you'll get crystals on it's walls, these are the equivalent of snowflakes, just attached to the inner wall.
