Ha! That was a common competition between me and my friend around that age too.
He is very fortunate to be part of a reasonably affluent family, so he had like 6 60-liter boxes full of assorted Lego.
We would spill a couple at a time (who am I kidding we spilled all of them) on the floor, when the flow of pieces stopped, the game was on! So many arguments about the nature of the simple shapes, like "oh no this isn't a blue lightsaber, it is a cylinder of pure diamond!"
