So you want to build a great snowman? Well, science has a lot to do with it. Here are four tips to help you better understand the physics and chemistry behind achieving the perfect ice sculpture, according to Lifehacker:
- Snow matters: Snow comes in five different types, each with different water contents. Avoid using dry snow or slush to build a snowman, focusing instead on using moist or wet snow, with no more than eight percent water content.
- Location: Build it on level ground, and make sure it is blocked from the sun by a building or hill so it's less likely to melt. Don't build it on asphalt or your driveway.
- Shape matters: Spheres are the best body shapes for a person made of snow. Layer the largest spheres on the bottom, the medium-sized ones in the middle, and the smallest on top.
- Size matters: Don't make your snowballs too big or your structure will be unstable.
