Different types of brick tubes (hollow vs. solid)
I'm currently going through a Lego lot with a variety of standard bricks (2x1, 3x1, etc.). For the first time ever, I've noticed that there are two types of those bricks - those with a hollow tube and the bottom and those with a solid tube. Please see the picture below.
When breaking the lot into the individual sets, I obviously don't want to mix those two types (i.e. a set should only feature one of them). Is there any way to distinguish whether a given set did originally contain the hollow or the solid bricks? In the instructions, they are only listed as 3004 (using the 2x1 as an example).
