you can use plastic, thick paper, etc. It is always best to keep the rocket light!
What materials do you need to build a water rocket?
There are two materials that i have ever seen a rocket made out of they are...wood and steel.Steel is medal
you put fins on the rockets
the rockets on the fin are over 50 feet long and this so the rocket will be stable during flight
how to make a rocket exploud
No
with bits and bobs
Wood or plastic.
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.
To keep your rocket in the air for long, use larger fins at the tail end.ANS 2 - Fins don't make the slightest difference to flight time. -You need a longer burning motor.
you put fins on the rockets
Angle the fins so it spins, like a screwdriver
because if thay are in the wrong place the rocket will not be stable
There are several materials you can use. Plastic assignment folders make an excellent fin because they are light weight and more durable than paper. Corriflute (Correx) is also a great material as it to is sturdy. (i am assuming you are building a 2 liter water bottle rocket) Avoid using paper and card board as the water can damage the fins making them anti-productive.
It Can Cause The Rocket To Spin Out, and/or wobble of course
the rockets on the fin are over 50 feet long and this so the rocket will be stable during flight
Because the fins and motor thrust make it go up, if aimed up.
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
You do this through experimenting with your rockets. Larger fins make their flight more stable, but slow them down a little. Very small fins make them fast, but often too unstable so they spin and corkscrew. So you aim for something in between, that suits your rocket and the motor.
