345 balloons. I hope that answers your question.
258 helium filled balloons filled to 34 psi each
486/18 = 27 ballons each
5672-
26 clowns
easy, divide 486 by 18, i could do that without a calculator if i could be bothered, but by using a calculator, it is 27 balloons each.
One would not need to purchase an M9 pistol. One may want to purchase an M9 pistol so they can go target shooting with it. Target shooting is a hobby many enjoy.
so it will fly.
At least one for each guest. Two for each guest is even better.
Depends entirely on the pistol. I have a single shot muzzle loading pistol that 2 shots a minute would be good. A fully automatic machine pistol can fire more than 100 rounds per minute. You need to specify WHICH pistol, as there is no one answer.
You cannot prepare helium balloons too far in advance. You should prepare these balloons hours before the event you need them for.
Yes.
