Not sure about your calculation. The current gear that make the spark float is 6cm x 5,5cm. how many grams would that be good for? According to your exemple, that would be 4 x 45g, which is only 180g. So according to this, it should not make the spark float but it does make it float no problem. Something does not add up here.
ok, I did a quick google (for you):
a 3cm ball will float just 14g
a 4cm ball 33,5g
a 5.5 cm ball 87gr
and a 6 cm ball 113
And that always means, the "thing" on top of the ball is touching the surface!
Which would explain, to me at least, why the "water-landing-gear has a diameter of 5.5 or 6 cm
To make sure that the Spark, which has a floating volume too, of course, will stay away from the watersurface
Every video I have seen, so far, the balls where just about half in the water
But since you have care refresh and only dont want it sink:
Why don't you put your 4cm balls in a washing mesh, together with a sunglass cover/box.
In this box you put about 300gr of something (that fills the volume a bit!) and check out what is happening, as soon the air bubbles out ?
