2 liter bottle rocket designs how to#
You can find full instructions on how to create a bottle rocket with baking soda and vinegar from Green Kid Crafts here. Instead of using air pressure from a pump, this rocket builds up pressure from a chemical reaction. Begin filling the rocket with air and once the pressure builds up, the rocket will blast off! 2. You’ll also need a needle adapter for your bike pump. Use a cork and duct tape to create a tight seal for your nozzle. In this experiment, you’ll fill your rocket slightly with water. This is the classic water bottle rocket experiment! You can find the full instructions here from Science Sparks.įor this project, you’ll need a plastic water or soda bottle, bike pump, construction paper or cardboard, a cork, and duct tape.
Classic Water Bottle Rocket Source: Science Sparks Let’s jump into three variations on how you can create your own rocket out of a water bottle or other plastic bottles.
3 Ways to Create Your Own Water Bottle Rocket Once air starts pumping into the bottle, stand back, even if nothing happens right away! Everyone should wear safety glasses. Your children should not try these projects alone because of the extreme force involved.
Launch pad – cardboard box, bricks, stonesĪlways use water bottle rockets outdoors. Nozzle – bottle neck opening, cork, garden hose connector (Gardena quick connector). Gas – bicycle pump, air compressor, compressed gas in bottles, or create a chemical reaction that will generate pressurized gas. Water – sometimes additives, such as soap or salt are also used. Rocket – one or more empty plastic bottles, typically a 2-liter soda bottle. But, in general, you’ll need the following to create your high-flying water bottle rockets! So, with that brief review of physics lessons in mind – let’s get started on our water bottle rocket projects! What You Need to Create Your Own Plastic Bottle RocketsĮach of these experiments are a bit different! They will create pressure in different ways so that your rockets can fly. The reaction, or motion, of the rocket away from the launch pad is equal to and opposite from the thrust of the engine or nozzle. The rate (speed) will be determined by two things: The mass (weight) of the rocket and by the force produced. How do Newton’s Laws relate to a water bottle rocket?įor a rocket to lift off, force must be exerted. These always come in pairs, and if one force is stronger than the other one, that object will move. Newton’s Third Law of Motion: For every action, there’s an opposite reaction. Newton’s Second Law of Motion: Acceleration of an object is directly related to the force exerted on the object and oppositely related to the mass. Newton’s First Law of Motion: Objects at rest stay at rest, or objects in motion stay in motion, unless acted on by a force. But first, let’s do a quick review of Newton’s Laws of Motion. These projects are great lessons in physics. The water is forced out by the compressed air. These model rockets use 2-liter plastic bottles as the vessels and water as the reaction mass.
