LOL I HATE the CYA test! So that ^^^^ is what I came up with..........I call it the "bar glance". You don't stare, you just glance then look away, glance again to see if they saw you looking LOL
The dot should be gone when you GLANCE in the tube. If you stare you WILL see it even if you cannot see it LOL One person had an idea I like also. Pour it to each level and the the glance in and out. If you can see it go to the next level, etc until you reach a level where it cannot be seen at a GLANCE. Call it that level.

I like that idea!
