If you were to graph particle size and porosity, it would be a constant slope (horizontal line).Porosity is not affected by particle size.

It would depend on the size of the tennis balls, but assuming a standard 2.63 cubic inches per ball, you would need approximately 122,321 tennis balls to fill 106.6 cubic feet.
You just stack them ontop of eachother, except more carefully that it would with 3 balls
The bottle of helium gas would weigh less than the identical bottle filled with air at the same pressure. Helium is less dense than air, so a bottle filled with helium weighs less due to the difference in density of the two gases.
You can always buy them online, or at least at most tourist beaches. That's because water filled balls are common to use in the sand. (I would imagine)
No, soccer balls are filled with ordinary air If they were filled with helium, they would float into the skyHelium filled soccer balls would certainly not "fly into the sky"! The difference in mass of an air filled ball and one filled with helium would be but a few grams! But the helium (having a much smaller molecule than those that comprise air) would leak out of the bladder more quickly. In addition Helium is much more expensive than compressed air.
They would be way too heavy if you fill them with water.
A variation in aggregate side (well graded) allows the concrete to be more dense, which means less voids, which allows for stronger concrete. Think of it this way. If you had a two rooms, and you filled one with just basketballs and the other with beach balls, then basket balls, then baseballs, then golf balls, then bee bees which would you think would be filled more. The one with the varying sized balls.
Porosity, or empty space may used in fields like ceramics, pharmaceutics, manufacturing, engineering, and soil mechanics. Each field has different scenarios when porosity would be used.

tickle my balls
the woman who lives a life filled with denial and envy.
This is because without the roughness, being able to grip the ball would be hard. Slick balls are not easy to grasp. Grasping rough balls is better.
round particles of the same size.
I would go with sportco juggling balls which can be found on http://www.sportjugglingco.com/ because they are high quality and durable and you can have them under filled to your specifications. (mine are 10% under filled.) I have also heard good things about the sil-x balls which can be found on http://www.thewjfstore.com/. If you are a beginner stick with hackey sacks.
The air layer will improve the thermal insulation.
