@Sun Ogong: Yeah, your numbers are right, I think. Maybe shrink the sphere. 35cm radius is a 70cm diameter, which is a fairly large object to hold in one hand.
Granite has a density of 2.75 g/cm3 (source: googling granite density and putting what google says)
A sphere of radius 35cm has a volume of 4/3 * pi * 35^3 = 179594 (...) cm3
So it will have a mass of 179594*2.75 = 490000g or 490kg (2sf)
So maybe decrease the radius. What's the largest mass you reckon you could throw?
