Ernie Keefler needs your help! Someone has snuck into the Keefler Bakery and messed with all the baking powders. They have left a hand-written note along with three mystery bags of white powder. Ernie Keefler’s™s investigation team has gathered up samples of different white powders found at the Bakery along with samples of the three mixtures and the hand-written note. Using Chromatography and other simple Analytical techniques you will crack the case and figure out which mystery mixture is the cookie recipe and whodunnit!
