Mobile science lab trains teachers in Willmar
WILLMAR -- Extracting DNA from pieces of fruit required a group of middle school teachers to squish the fruit with other ingredients, strain it through cheesecloth and then add alcohol.
The end result was a small glob of "snotty goo" clinging to the end of a pointed stick -- the DNA.
It looked gross. And the teachers were sure their students would love the whole thing when they get a chance to try it themselves during the school year.
