Science Fair Winners

Wife's 11th year to sponsor the St. Joseph Homeschool Science Fair. For Meggar's grand finale, she heated pretty blue water over a Bunsen burner and little copper flakes precipitated. Using $10 worth of Copper Sulfate and granulated Zinc powder, she was able to produce about 4 grams of copper flakes.
Dorito's Chemistry experiment stole the show when his explosion sent two dozen sparks flying about five feet into the air! He was hoping to win first place because: "Boys like to blow things up!" But the judges gave him 3rd place for his dangerous elements in the high school division (that's still good IMO). He put sodium metal and potassium metal into H2O to create two violent displacement reactions.
