Fin design :)

Other side of our fins!

Our blueprint

Almost done...I love all the glitter!!!

I can't wait to attach our fins tomorrow...I hope it works as planned! [fingers crossed]

Day 1: Designing.

Our Blueprint.

Emily, working hard . (;

Our competition, James Moore.

Today we did a lot of designing and actually starting to build our rocket.  First, we drew our blueprint.  In our blueprint, we have one bottle going inside of the other with a rubber band ball in it.  We then measured all of our distances and started to assemble.  From Emily's research, we found out that we need a parabola shaped nose cone so we constructed one from cardboard, ductape, and the remanning bottle.  From my research, we concluded that to be more aerodynamic and try and minimize drag, we needed to use 3 triangular shaped fins instead of 4.  After, we got the rubber band ball and stuck it inside of the nose cone.  I'm looking forward to seeing how our constructing goes today and what else we can accomplish.
