That was not a normal M1000. It was clearly (badly) hand made or modified. I know this because I used to make fireworks as a hobby until the ATF started hiking it's skirt up and doing the mousey dance every time someone sneezed.
This is an actual M-1000.The message is clear, don't set off fireworks on the patio furniture.
Some of the ones I made might BARELY qualify as a small bomb but those involved 4 oz. of black powder and a well reinforced tube.
You should note that commercial fireworks are mortar shells, not skyrockets.
Now, how many times has your house burned down in all of that? How many skyrockets in your windows?
I can understand you not wanting it daily for months, but surely on the actual holidays it might be nice to not get all bunched up over it.
