Same (though, my physics background is much weaker than yours). However, I'm mad about two things in the headline and lay-article. The headline says "shaken hard" and the image caption says "obtained by putting ice in a bowl with steel balls." The article is clear, they put ice in a ball mill. They ground the ice up at low temperature. They didn't just shake it, they didn't just put ice and steel in a bowl. Jeez.
