As the school year continues to heat up, it's time to start thinking about this year's science fair. Here's a list of science projects that will help you win the science competition at your school:

• A homemade volcano, but you add chunks of hot dog to the baking soda/vinegar mixture to get texture and flavor
  
• Use your homemade potato battery to send an electric current through your braces. Then tell people at your table, "My mouth's an outlet, plug in your phone."
  
• In front of poster that says "What would life be like without photosynthesis?" place two pizzas side by side, one with green peppers and one without.
  
• Just put out a clear plastic case and label it "air."
  
• Perform the most challenging live science experiment of all—seeing if you can get your parents back together at your grade-school science fair.
