Hello,
I attend a physics club at my school and now, we are building rockets until winter. I need some help because I really want to beat the GCSE students. We are in self chosen teams and the winner is who gets their rocket the highest(hopefully it will go high enough so we can't see it)
I have already gathered some information:
I should have a rounded nose for the rocket(decreased drag)
Centre of mass should be towards the tip (increase stability)
Placing fins at the bottom increases stability.
My current thoughts for fuel are:
Water
Vinegar and Baking soda.
Is there anything else I could use as a more powerful fuel? *I am in the UK so therefore, I cannot use solid fuel*
Should I 3d print the rocket, or at least attempt to? (most people will be using bottles so I hope I can do something different)
How do water rockets work? I can't wrap my head around how to push the water quickly.
What is the optimal fin shape?
Any other advice and things I should know? Help is greatly appreciated!
