Not Accurate
However, because the spheres don’t appear to be very large, you may have to squint to see them. That is not the case! Keep in mind that some of them are hundreds of feet in the air, so what you see on the ground isn’t an accurate representation of their true size. Some of the larger varieties have a minimum diameter of 36 inches.

Different Sizes
The balls that hang a little closer to the ground – say, less than 50 feet above where you stand – may only be 20 inches in diameter. These are given out less generously than their larger counterparts. The smaller spheres are 30 feet apart, while the larger ones are 200 feet apart.
