Alliya, Joy and I made a boat together in Science. We mainly made it out of two cups, styrofoam and tin foil. The cups help catch as much of the wind as they can so it will help push it to the end faster. One struggle was getting it to go straight. It kept wanting to turn to the side. After the first trial we changed a few things. We had the cups turned sideways, but for the second trial we turned them the same way. Also for our second trial we added a few Popsicle sticks on both sides to add some wait to the boat.
