We're only going to tell the materials. You tell us how you did it!
Did your Ski Boat Air Jet break the sound barrier? Or did it make like a dingy and putter around? Could it race with the dolphins or will you need to recruit some guppies to tow it to shore? Now it's time to experiment. Think of a question you want answered. Like, what would happen if you use something heavier than a styrofoam meat tray? Would your boat break a speed record or end up in the shipyard? What about changing some of the other materials? What happens? Be sure to keep track of what you think is going to happen. Then, test it out and send your reports in to our special feedback area. Every week, we'll publish a whole bunch.
