This is the final report of physic that we do in the water rocket and the competition of water rocket. This competition was interested because this work can change the pressure, water and angle.

Hypothesis
Resources:
Material: For water rocket:
2 Bottles Paint Tapes Scissor Knife Folder PVC For the competition: Water Beaker Shuttle Soccer field or open field. Cone Design experimentation: For water rocket:
For the competition:
Step: For the water rocket:
Cut the First Bottle
In this step you will have to use an Exacto knife to cut out the center of the first bottle. Look at picture to see where to cut. Make sure you keep the top and bottom leftover from cutting out the center. Step 2Attach the Bottles
Place the middle of the cut bottle on the bottom of the second bottle and attach using duct tape. Make sure the two pieces are securely attached. Step 3Adding the Fins
Take the manila folder. Along the folded side, cut three triangles so when they are opened, they appear as diamonds. Fold the edges of the fins so there is a flat piece that will be taped down to the bottle. Attach the fins to the bottle using duct tape. Step 4Creating the Top
Creating the top of your rocket is really simple. All you have to do is take the top of the first bottle you cut and attach it to a foam cylinder using duct tape. Then take a piece of foam and place it under the top of the bottle. Trace the outside of the circle on the foam. Cut out the circle with the Exacto knife. Use the outside as a skirt and place it around the cylinder, attach using a stapler. Step 5Inserting the Elastics
After creating the top, create 6 incisions using the Exacto knife, spread equally apart, around the top part of the cone. Then cut each elastic band so they are straight lines. Slide the rubber bands through the incisions. The first one through the first incision, and through the incision across from it; the second one through the second incision, and through the incision across from that; the third through the third incision, and through the incision across from that. Pull both sides of the elastics up over the top of the bottle and screw on the top to hold in place. An asterisk should appear in the inside of the top of your cone. Pictures:

Conclusion: I learned to make a water rocket and found it interesting activity we had in the competition. I managed also to water the rocket had to touch the flag or the circle. In the first time I released the rocket almost hit in which he had to change the amount of water, pressure and \ or the angle. Since a person in our group won the competition and at night I went to the football field to see Mr. Alfonso launching the rocket that he had with lights and Parachute.
