Fins were widely popular in the 1950s and early 1960s. For a prime example, look at the 1959 Cadillac DeVille.
Wat is the disadvantage to having 4 fins on a rocket.?
Because of the changing times.
During the 1950's, many colorful American cars, such as Oldsmobile, had huge fins. They also had shiny metal bumpers and bright lights fitted to them. Some of them looked more like alien spaceships than cars!
Because they wanted to copy the shape of jets and rockets
On cars that have them they are air cooled since there is no radiator.
the best fins for a bottle rocket is having four fins located at the bottom of your bottle rocket the shape of long triangles ! ! ! :) hope it helps !
Having fins will give you more control. Without fins you will be able to do surface 180's easier and landing tricks will be a little more forgiving.
Fins are used to help keep a rocket stable. The only way to find out if more fins will make it more stable is by testing it.
it would have more control.
By eating the guppies, yes they were have increased.
When they are young they are OK but as the young males start to develop they will start to fight. I found the best way to avoid damaged fins from fighting is to keep a very close watch and as soon as you think a fishes fins are getting a bit bigger than the others around it, assume it is a male and put it in its own tank. If you are wrong it doesn't matter, because it can be put back it it's a female but if you are right you have stopped the fish having damaged fins which lowers its value.
