They should be cut into triangles and place perpendicular to the rocket. This will give it greater stability when if flies into the air. Place the narrowest part of the triangle towards the top of the bottle and the widest part towards the bottom.

What are Balsa Fins?
Balsa fins refer to the fins that are made for model rocketry and are cut from balsa wood. These are glued or cemented onto the base of the cylindrical part of the rocket. They are crucial to the flight stability of the rocket.
What do you use for fins on a hydro rocket?
wht can i use for fins on a hydro rocket?? i am a student and i need help you can try cardboard, plastic, or cut CDs. they need to boe in triangles to fly high.
What is the procedures for a water rocket?
take 2 l. bottle cut the bottom of a bottle off put the 2 bottles together take a piece of balsa wood and make the wings fill the bottom part of the water rocket with paper put the wings on the bottle rocket cut a circular cup in half put a tennis ball on the cup
How would you make a good bottle launcher?
# Remove the label from the outside of the bottle. Take a cloth and some paint thinner to remove the sticky portion of the label. This may take a while and a lot of rubbing. # Decide how many fins you would like. Four fins are easier than three, but if done correctly either way works well. The fin shape is also up to you. See the diagram for the easiest fin shape. Next, trace the fin design out on the balsa wood sheet and cut the desired number of fins out from the sheet. Make sure that the grain of the wood is running parallel to the leading or trailing edge of the fin. If this is not done, the fin may rip apart in mid flight. Lightly sand the fins so they become smooth. # Now, it is time to mount the fins onto the rocket. Take a piece of paper and wrap it around the lower portion of the bottle (near the opening end). Mark the circumference of the bottle where the piece of paper overlaps its self. Remove the paper and measure the distance to the mark that was just made. This will tell you the circumference of the bottle. If you are planning 4 fins, divide the circumference by 4. Use this number to divide the piece of paper into four equal sections and mark the sections. If you are planning for 3 fins, use the same process, but this time divide the piece of paper into 3 sections. Wrap the piece of paper around the bottle as before and secure it with a piece of tape. Take a felt marker and transfer the section marks on the paper to the bottle. These marks designate where the fins are to be placed. Make sure everything is perfectly even, or the rocket will not fly well. # Next, take a straight edge (ruler) and draw a line through the mark that was made so you will have a guide-line for fin mounting. Apply a rubber-based cement to the fins, carefully aligning the fins with the straight lines you have just drawn. Press the fins down onto the bottle and use a piece of tape on either side of the fins in order to keep them straight while the glue sets. It is best if only one fin is done at a time and the fin is kept vertical until the glue has set. Make sure all of the fins are perfectly straight. # The final step is to cut the manila folder into a cone so that it will fit over the top of the bottle rocket. This will be the nose cone. Cement the nose cone to the top of the rocket. If you wish, a parachute can be added. The rocket is now finished. Make sure all glues have dried completely and the fins a securely attached to the rocket before it is flown.
Why do you put water in bottle rockets?
A 2-liter bottle will be required, as a 20-ounce is too small. Remove the label and take the cap off, but save this cap. take a pen apart and saw the barrel of the pen in half. Outline the size of the barrel on the top of the cap. Drill a hole this size into the cap. Using cardboard paper, construct 3 or 4 fins for the ship. A foam football cut in half can make the nosecone of the rocket, but a piece of paper can substitute. Once the nosecone and fins are attached, put the pen barrel in the bottlecap, and attach a bike-pump to the pen barrel. Fill the rocket with water, put the cap on, and pump air into the rocket until it blasts off.
Do they cut fins from the Killer Whales in the Tundra?

How many fins should you put on a long range bottle rocket?
easy! get some balsa wood and a modeling knife!and cut out a simple shape!balsa wood is ok because it is light in weight, however, if your rocket has a crash landing the fins will not likely survive. I suggest something a bit more sturdy. on some rockets i have used chucks of CDs as fin material (they're harder to snap than you would think) i would also suggest arrow glue ( like the glue for archery arrows) as an adhesive for fins shape? i would check out this web site. the fin designs are not difficult to create and the shape is backed up by the Reynolds number don't know if you know any thing about that http://www.apogeerockets.com/technical_publication_16.asp.best of luck! :]
How do they cut the fins of the killer whales?
They cut it with a knife
How can i build a water bottle rocket?
you get a two liter then you live one untouched the other you cut the tip off then make a parachute then contact it
How do you put a parachute on a bottle rocket?
The best method is to tape the parachute to the side of the bottle and stuff it inside of the nose cone. The nose cone should have string connecting it to the rocket, yet, the nose cone is not actually taped to the bottle. It should balance on: a) Tabs (Cardboard) b) Just have it firmly on top of the top of the bottle This way, the rocket will soar straight up (hopefully), the nose cone will detach (but stay connected), the parachute will fill up with air and expand, and your successful rocket will sink to the ground at about 2-6 mph.
What is a model rocket fin design?
Usually you would put the fins at the bottom of the body tube and evenly spaced around it. The rocket may be stable even though the fins were a little higher on the tube; it depends on the location of the Cg.
How do to make a bottle rocket?
You can strt by first constructing the rocket body. Using a sheet of computer paper build the body of the rocket and fold it half lengthwise. Cut the paper in half as folded and then take one half and fold it further in half, do it cross wise. Now you should have one half of the original sheet along with two quarters of it. Fold one of the quarters to half and fold in half one more time but diagnally. Cut along the creases which is created from the folding in order to create four triangles which can be used for the fins. Now you have to take the other quarter and draw a circle on it. Cut it out and mark its center. Sketch two lines which should form a right angle from that point. Cut out the portion marked by those lines and make a cone out of it. Next, take the half of the paper and tape it around the canister. You need to place the canister along one of the edge of the paper and make sure that the opening of the canister should point outside of the cylinder formed by the paper. Now, tape the fins on the part of the cylinder paper which is near to the canister while tape the cone on the other end. Hope this helps.
