Anyone who has tried to have a snowball fight, or build a snowman only to have the snow fall apart in their hands, will know that some snow is better. That\u2019s because the properties of snow vary greatly depending on temperature and moisture.\u00a0<\/span><\/span><\/p>\n The best snow for building snowmen is moist or wet snow, which forms when the air temperature is just above freezing \u2014 between 0\u00b0C and 2\u00b0C \u2014 meaning that some of the snow melts, creating free water between the ice crystals that acts like glue. Ideally, the snow should be around 3 to 8 per cent moisture. Any more than 15 per cent moisture, and snow becomes slush and too wet to hold a shape.\u00a0<\/span><\/span><\/p>\n Freshly fallen moist or wet snow forms as dendrites<\/a> \u2013 the classic branched snowflake shape \u2013 and the branches provide more surface area for the water \u2018glue\u2019 to stick to, making this type of snow ideal for snowballs and snowmen. When temperatures drop well below freezing, there is little or no liquid water to act as glue, and the ice crystals instead tend to form as flat plates, which have a lower surface area, making them less sticky.<\/span><\/p>\n There are other things to consider when building a snowman. You\u2019ll want a level area of ground; ideally not a driveway because tarmac tends to absorb heat, which can melt your snowman prematurely. Similarly, building your snowman in a shady spot will help it last longer.\u00a0<\/span><\/span><\/p>\n Start by packing a ball of snow in your hands. The warmth and pressure from your hands will slightly melt the snow, creating more watery glue to hold the crystals together, which will refreeze once you\u2019ve finished building, making the snowman stronger. Roll each ball across the snow, aiming for a roughly 3:2:1 size ratio for the base, torso and head to maximise the snowman\u2019s stability. Slightly flatten the top of the ball before you stack the next one on top, and reinforce the base of the snowman by packing extra snow around the bottom.\u00a0<\/span><\/span><\/p>\n Read more:<\/strong><\/p>\n Asked by: Glyn Ellis, Cardiff<\/strong><\/p>\n To submit your questions email us at questions@sciencefocus.com<\/span>\u00a0(don\u2019t forget to include your name and location)<\/em><\/p> <\/body><\/html>\n By Dr Claire Asher Published: Friday, 16 December 2022 at 12:00 am Anyone who has tried to have a snowball fight, or build a snowman only to have the snow fall apart in their hands, will know that some snow is better.
