CELINA - Two Coldwater seventh-graders got to see the final version of their science, technology, engineering and math challenge design on Thursday before it was put into use at PAX Machine.
Lucas Pohlman and Keegan Bruggeman were shown the final design of their shaker tray holder, engineered by Allen Hartings, as it will be put into use. Pohlman and Bruggeman's design was picked out of about 15 groups of seventh-graders who had been presented with a problem from PAX Machine last year.
