Growing up, I considered my snowman a success if I didn’t knock the head off when inserting its carrot nose. But, if you’re going to do something, you might as well do it right!
SmithsonianMag recently published a story on the science behind perfecting your snowman.
First, let’s talk about the snow. “Snow can either be too wet or too dry,” points out Dan Snowman, a physicist at Rhode Island College in Providence. Scientists actually classify snow based on its moisture content—the amount of free water relative to ice crystals—not to be confused with the amount of water the snow would produce if melted. Snow comes in five categories: dry (zero percent water), moist (less than 3 percent), wet (3 to 8 percent), very wet (8 to 15 percent) and slush (more than 15 percent).
By that scale, moist to wet snow is ideal for snowman building, according to Jordy Hendrikx, a snow scientist at Montana State University. Dry snow is like a loose powder with particles that don’t stick together very well, while slush is too fluid to hold a shape. “You can think of the free water as the ‘glue.’ You need enough to stick the crystals together, but not too much. Otherwise it won’t form a solid snowman,” says Hendrikx.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
