Mr. Science
Is there a way to check for a vacuum at home? (I don't mean a pager attached to the ol' hoover.)
We just bought some "Touch 'n vac" containers that keep food fresh by forcing all the air out of them. Or at least, some of the air. I'm just wondering how much more efficient our seal-a-meal machine is. I'm sure it is more efficient, I am just curious by how much. There is enough of a vacuum both to keep the lids on, and to help keep foods fresh. But how much of a vacuum is that?
Intellectually I know better, but I keep expecting to see a visual change when we create the vacuum. Ron agrees. We both think the vegetables should float around or something. Strange how the Apollo missions and sci-fi movies have trained us to see vegetables in a vacuum sealed container and expect them to behave like they are in an anti-gravity chamber.
I am somehow doubting that the test will involve anything like the die tablet you use to check if your toilet is leaking.
