Re: Bottle Rocket B
A backslider is a type of rocket where you balance the weight of the top and bottom so that it will be launched go up and "slide" back down on its side

Re: Bottle Rocket B
See Robert Youen's bottle rocket page. He's not updating it anymore and some of the links are broken, but it still has some good info.quizbowl13 wrote:what is a backslider, and how does it work?

Re: Bottle Rocket B
For my school, this is our first year of bottle rockets and I get confused easily. I know I should do my research, but is there a basic summary of the event? I would be grateful for help.

Re: Bottle Rocket B
While browsing the internet today, I came across, what seems to be a fairly comprehensive water rocker website: Air Command Water Rockets. I only spent about 10 minutes checking it out, but it seems pretty good at first glance.

Re: Bottle Rocket B
Quality of the launchers will likely vary from competition to competition (most places will probably reuse last year's Egg-o-naut launchers). Still, launchers at comp should work decently well, considering I was able to build one (based off of this design) with about $50 worth of stuff and a couple hours.
As for your second question, the rules say and I quote, "Timing begins when the rocket separates from the launcher and stops when any part of the rocket touches the ground, goes out of sight [probably added because of Solon's amazing 10-minute flight at Nats last year], or comes to rest on an obstruction (e.g., a tree or building)." So yes.
