![]() ![]() The density gap in amorphous ice was fairly fundamental to our understanding of water. In the near-vacuum of space, however, ice is usually amorphous, because the atoms don't retain enough thermal energy to wiggle around into a crystalline structure. That's why snowflakes tend to be hexagonal. ![]() Here on Earth, ice naturally takes a crystalline form, with its atoms arranged in a repeating hexagonal pattern. This is why ice cubes float in your drink.īut not all ice is created alike. Water does the opposite: it becomes less dense, meaning water ice is generally less dense than water. Our existence depends on it, we launch space missions searching for it, yet from a scientific point of view it is poorly understood," says chemist Christoph Salzmann of University College London.Īnd its density under cooling conditions is perhaps the weirdest thing of all: as most fluids freeze, their density increases. Researchers led by chemist Alexander Rosu-Finsen, formerly of University College London in the UK, have named the new form medium-density amorphous ice (MDA). The new ice has a density of 1.06 grams per cubic centimeter – clocking in incredibly close to the density of water, at 1 gram per cubic centimeter. That's because its atoms are arranged not in a neat repeating crystalline pattern, but jumbled up all higgledy-piggledy, an atomic omnishambles.īut the amorphous ice emerging from the team's experiments, a process called ball milling, is unlike any amorphous ice ever seen.Īmorphous ice is usually low density, around 0.94 grams per cubic centimeter, or high density, starting at 1.13 grams per cubic centimeter. ![]() I put in some funny items like sunscreen since we’re getting married at the beach (more on that later), nautical earrings, lots of Sticky Grams (Instagrams made into small magnets) of our fun times together, college memorabilia, mini Steelers umbrellas and footballs since I have some die hard football fans like myself, and I even found an old note one of my best friends wrote me in middle school that I folded up and included in hers.This is amorphous ice, a form not found in nature on Earth. I laughed and cried thinking about various stories from the past with each of these girls. Making the surprise balls was such a fun walk down memory lane. so I decided to mix it up a bit and do some surprise balls and some custom cookies. I immediately knew I wanted make these for the girls BUT then, of course, the internet exposed me to so many other ideas! I was torn. As you carefully unravel the crepe paper, small trinkets are unveiled along the way with a larger prize in the middle. They sold them at the Land of Make Believe in Hudson, Ohio where I grew up and I always got one when we were allowed to pick out one thing at the store. one of my favorite toys as a kid was a surprise ball. From girls I played softball with in middle school, met in my sorority in college, studied abroad with, interned and then lived with in DC, and of course members of both of our families, they have all molded me in so many positive ways and I needed all 12 of them. It was very important to me to have every single one of them in the wedding. Each of these 12 girls has had a huge role in my life and has helped shape me to be the person I am today. !īefore I carry on, I should mention I have 12, yes t-w-e-l-v-e bridesmaids. One of his friends told me that Matt basically said, “So, you’re in the wedding…” not giving much of an option or question. Matt, on the other hand, basically brought it up to the guys at an O’s game or in the middle of a crowded bar/concert. To me, this was the first creative aspect of wedding planning and I was excited to do something special for my friends. I took so long, that it was getting awkward as people kept asking if I had a bridal party yet. I spent hours, OK, more like weeks, thinking about the best way to ask my friends to be in the wedding. When Matt and I went to ask our friends to be in our bridal party I was reminded of that difference. Sometimes I forget just how different boys and girls can be. ![]()
