We let off some pretty big fireworks in our garden on fireworks night (5th November). A couple of the rockets had big sticks attached to them and weighed 1-2lbs each. I always worry slightly about where these sticks are going to land and wish that the last act of an exploding firework was to set off
a small charge to deploy a parachute to take the stick safely back down to earth.
Then of course, you could also have a firework which does something (anything from a simple shower of sparks to a whizzy Catherine wheel) while being parachuted back down. The general mayhem and traffic chaos when this gets blown off course onto a nearby road would be a small price to pay.
mine had parachutes.

A few years back we had a rocket which was supposed to shine brightly while parachuting back to earth. The parachute didn't open so it was a big disappointment. |
|
|
I used to chase those when I ws a kid and keep the 'chutes. My Action-man used the parachutes to make it safely down from my window to the garden. |

Sounds good. But what damage can a little stick really do? |
|
|
Never had one come down on your head, huh? |
|
|
One fired by my grandfather came back down through his shed roof. |

[britboy] Forgive the rusty physics, but the energy (exerted on your head) from a 10g stick falling from 300m would be
E=MGH=0.01*9.8*300=29.4N
This would be equivalent to a 1kg weight being dropped on your head from 3 metres.
A fair bit of damage, I'd say :) |
|
|
not to mention the damage if you were looking up with your mouth open in awe and it stabbed you in the eye. |
|
|
(now where's that other damned silly firework idea?) |
|
|
([reap] ...or a 1000kg weight from 3mm...) |
|
|
Given the choice, I'll take the stick with wind resistance over the large weight. |
