Visitors to the 2009 Iowa State Fair saw Michael Jackson's moon walk.
At this summer's fair, they'll see Neil Armstrong's moon walk.
I guess one moon walk sculpted in hundreds of pounds of unsalted butter just wasn't enough for Iowa.
Bakers prefer unsalted butter for its consistency. Salted butters vary in the amount of salt they contain, so by starting with unsalted butter, a baker can determine exactly how much salt to use in a recipe.
I wonder how much salt goes into a butter moon walk.
