How Do You Make Soda Bottle Motorboats?
Simple household materials will make these boats zoom. Wash out a 16-ounce plastic soda bottle. Gather the toilet paper, baking soda and vinegar. Lay out two squares of toilet paper. Pour several tbsps. baking soda on the toilet paper squares and fold them up to enclose the baking soda. Place these toilet paper “packages” inside the bottle. Have one person hold the bottle cap. Pour 1/4 cup of vinegar into the bottle. Place the cap on quickly and twist it only once. Place the bottle in the water in the wading pool or bathtub. Watch as the baking soda and vinegar have a chemical reaction and cause the bottle to move across the water. Experiment with different amounts of vinegar and baking soda to see how it affects the boat’s speed.
