Questions regarding rules
Posted: February 4th, 2020, 12:26 pm
So the rules say that no metal objects can be used, I'm wondering if that's just for the bottle or both bottle and parachute? I figured it mainly fell under the lines of structural integrity for the bottle and safety for individuals the bottle may land on, but is it a bad idea to staple the strings to the parachute itself?
I also have some questions regarding the nose cone. So it says that it needs to be "blunt" at the top and can't touch the inside of a bottle cap. So I was told that this is for safety, so sharp edges are also not acceptable, and that putting some duck tape around the sharp edges of a cut bottle to make it blunt might be acceptable. I wanted to check on this to see if it was accurate.
Another question regarding the cones. My partner once taped a rubber lego tire to the top of the rocket, that was big enough to allow the ping pong ball to sit securely on top but didn't hold it down. Because it was rubber it wasn't necessarily dangerous if it came into contact with a person at high speeds, so the only thing I'm worried about is whether or not it's an acceptable material/resource to use for bottle rocket cones?
