What can YOU do?

• Design your own milk carton boat. Figure out how many cartons you need to keep yourself afloat. [Hint: a half-gallon carton can float about 4 lbs.] Then, with an adult close by for safety, try floating your boat at the lake.
   
  
• How does the shape of a sail affect how well a sailboat zips along? Build a simple milk carton boat and make some different sail shapes to find out. Take it to a lake or pool when there's a nice breeze and see how well each sail catches the wind.
   
  
• If you know someone with a sailboat, ask to go sailing. Take a stick with a streamer attached. While you are sailing, hold up the streamer near different parts of the sail. What does the streamer show you about how the air is flowing near the sail?
