Estimating volumes

Good thing laboratory equipment is always labeled with the volume!

Even though I have played plenty with Legos as a child and am fairly good at 3D stuff, my mind just can’t estimate these volumes correctly. To me, the 500 ml cylinder looks a lot larger than 1 l volumetric flask and it blows my mind that if I fill the complete content of the cylinder into the volumetric flask, it is only half full.

Anyone else or is it just me?
