I know lower voltage requires higher amperage so much thicker power cables that take more resources but otherwise which system is safer to work with and which is more efficient?

If I so happened to attatch a mortar shell (the firework type that fire out of the tubes. Also the icecream looking shells(with the ball on top) not the cylindrical ones) to a model rocket. What would the expected outcome be when launched?

Mind you I have everything set up on the inside with the fuse connected to the engine. So after the engine burns up, the fuse will light, and somewhere between it's apex and the ground it should explode.

I'm just worried though that the top might be too heavy, so when launched it will lean and shoot in a different direction other than up.

I was wondering if the rounded nose of the rocket would make the aerodynamics worse, and if the top is too heavy. Because normally the bottom would be heavier due to the engine but such is not the case. Will it screw up it's flight path completely?

Would it also be a good idea to add fins near the top of the rocket? (currently it only has four on the bottom)

Any advice

If a sub-standard production method was employed, for indefensible reasons, then someone would be answerable, for negligence, or worse.

I am making a light using a LED bulb and a USB cable. i have tried a 47k ,100k and a 10k resistor and all resulted in low lighting. Is the Resistor the problem or is it something else? and if it is the resistor, then what resistance level should i use? i got the directions on how to make the Light from this site ( http://forums.pcworld.co.nz/archive/index.php/t-52676.html ) however i am not completely sure if all the directions are right.

In a wire (the positive), if i am correct, is where you put the resistor. However, does it matter which way the resistor is facing on a wire, such as 4th line comes first before the other lines.

This has got to be the most insane thing I have ever seen... its well over 800 Meters tall. (If it get's finished of course)

So tell me what you think. Is something like that really possible? Or will it crush itself?
