Multi – company ping pong balls for the close-packed model.?

I have to do a model at the macro level areas closed packed. I want to know is there an online store or somewhere in New York, where I can buy this type of ball. Basically, balls, I'm looking for is light and hollow, which can be moved easily if burnt. If not tennis, any other spherical object that is light, preferably hollow, generally across the diameter of a ping-pong or about 4 cm in diameter, and when it moves easily blown. Mainly we need spherical objects that are not too large, and come in different sizes. Moreover, for any better person with knowledge of the close-packed areas, this type of ball (tennis ball or a golf ball or Styrofoam, etc) would approach a macro level model?

For single size, ping pong balls are the best. For more Styrofoam in various sizes sizes should work.
