How to Make a Water Bottle Rocket

This implies that one unit distance on your drawing represents 1 m. You can use Play Doh, similar to the procedure for the one bottle rocket, or kitty litter. Figure 11 illustrates a well-secured launcher. There is a large force to start with but the rocket is heavy so it doesn't accelerate quickly. Flames, spots, checkers, glitter, etc. Write your results down in your lab notebook next to the measured angles. How will it work if you only use three straws for the nozzle? How much water should I put in? Then cut the triangles in half to make 4 right triangles.

It's more likely that the ground will damage the rocket, especially if it is concrete or some other hard material. The launcher is held in place by a U peg going over the launcher and pushed into the ground. Never stand over the rocket. Who knew that baking soda and vinegar had that much power? Observers should stand back several metres approximately 10m. This is equal to the volume flow rate of water exiting the rocket body.

As the water exits, the water height h drops. Left The rocket barely comes off the ground. Another member stood 30m away from the launch site to record the angle of the water rocket using a clinometer. You can find the mathematical formula linking distance, angle and height in the. Starting at the bottom right corner of the cardboard, roll the cardboard toward the left bottom corner.

The bottle flies off, leaving a trail of water behind it and probably soaking the person pumping too. What goes up, must come down. Water is propelled out of the bottom of the bottle by pressurized air encapsulated above the water in the bottle. Measure off 23 m, starting from the launch location in the direction at a right angle to the wind choose one of the two direction in which the person's arms were pointed when stretched out found in step 3. Note: In case your location has no access to water, take about 4 gallons of water with you.

For stability and security, the minimum number should be 3. I used a Pepsi bottle, so again, you may need to adjust the curves to fit your bottle. Instead, you can use a graphical method, as explained in the to convert angles to height or ask a mathematics-savvy person to create a conversion table for you. Virtually every object that you see around you has passed through the hands of a mechanical engineer. Beware of hot glue guns for attaching parts on a water rocket. This way, you will have enough time to step away from the rocket before it explodes.

The Science Behind It When water and antacid mix, carbon dioxide gas is produced. Baking soda contains sodium bicarbonate a base. At full force, two firefighters are needed to hold the hose, as shown in Figure 3. The launcher shall hold the rocket to within 30 degrees of vertical to ensure that it flies nearly straight up. Also note that we are assuming a thin-walled rocket body in which the dimensions d, L, h, and s are approximately the same with negligible difference whether measured from the interior surfaces of the rocket body or from the exterior surfaces of the rocket body. In case your rocket does go higher, increase the distance between the observer and the bottle rocket launcher for all your measurements.

Before you start pumping, make sure the area you are firing into is empty of people, animals and breakable objects. Allow to stand for three minutes, then peel off the label. Part A: Cut out the fins and nose cone templates from the printout. This force is then transferred to the rocket. This excess weight will mean that it doesn't accelerate very fast. When pressurization is complete, everyone should stand back for about 10m for countdown.

Looking into the sun can damage your eyes. By Newton's second law the one-dimensional force balance for the water rocket is where g is the acceleration due to gravity 9. Create the nozzle by taping four drinking straws together. Be sure to check the formatting, including capitalization, for the method you are using and update your citation, as needed. Squeeze out a small amount enough to do one fin. If you do not experience lift off, call your teacher.
