258 helium filled balloons filled to 34 psi each
486/18 = 27 ballons each
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.
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.
so it will fly.
At least one for each guest. Two for each guest is even better.
The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
Yes.
You cannot prepare helium balloons too far in advance. You should prepare these balloons hours before the event you need them for.
