Are you joking or what?

I can't hear any at the moment, but it is raining a bit.

How high do Rockets go before going boom? Very high i think.

With the explosion pushing the wood down and mavity on its side it was going down very very fast.

Can anyone else explain to this guy what i'm trying to say? I really cannot be bothered...
 
I'm driving to a location so secretive I don't even know where it's going to be yet, late at night though.
I know it's going to be flat, up high and have little light pollution.

8 lads and £400 worth of fireworks though, it's going to be interesting to say the least.

Oh and a tip I learned once, you know the fireworks you're supposed to bury up to a point in the ground, don't bury it the wrong way up or you end up blowing a gigantic crater in the grass :D

Terminal velocity would be relatively low for a small peice of wood. So it doesn't matter how high the rocket went as long as it was over 15m or so the stick would probably hit terminal velocity before hitting the ground/person.

Assumming a 100g stick, with a density of 300kg/m3, drag coefficient of 1 and cross sectional area of 1cm2 gives you a terminal velocity of 8.1m/s or 18mph. In short, not really fast enough considering it's mass to do any real damage to a person.
 
Don't get me wrong chaps - I'm all for having the fireworks tonight when you can see them. It's just when they go off for days and weeks around this time of year even in the daylight when you effectively cannot see them, it tends to get my goat. It's just... pointless.

It's stopped now though, so they must've heard my angry typing and got the hint.

Unless your unlucky enough to be looking up at the time and it hits you directly in the eye :eek::D.

Rockets...Wood Attached to Rocket as we all know.

blasts up 400+ Meters.. explosion.. the wood stick is still in the air very high up and falls and get pushed by the explosion alone...

It comes down just like a arrow and misses me by inches, all i heard was a quick zip as it was going so fast and it was nearly half way into the ground.

If it would have hit me i wouldnt be here today.

You can make all these sums up of mass and velocity but you dont have any field experience like i did that night

Hahahahahha, awesome. I wish I was as intelligent as you.
