i must praise your choice of words here. And what's more: the wording is correct.
Without the tube working as a "container", the whole vaccuum would cease to exist, so it really "contains" "a vacuum". It sounsd silly: serving as a container to hold "absolutely or almost NOTHING AT ALL"
Reminds me of old april-1st joke, praising the sales of (tiny like 5ml) bottles "of liquidified vacuum".
Liquid helium in a bottle is awsome, but liquid vacuum would be ... Harry Potter. Ever thought what happns, when you "spill" a drop of condensed vacuum? It would instantle expand, "filling" the room as vacuum restist pressure from other substances. So it instantly empties the room, taking away: the teacher, the blackboard, your lunch box (don't spill the stuff before you ate your lunch) and ... unfortunately: you too.
And, if it doesn't suck YOU up, it does suck up the air that before filled the classroom. But with a vacuumon the inside, you cannot open the classroom door any more (unless it opens inwards, then it will FLY open)
One of them smielys is for down-under, choose freely which one. |
