She Don't Use Jelly Lyrics
I know a girl who thinks of ghosts
She'll make ya breakfast
She'll make ya toast
She don't use butter
She don't use cheese
She don't use jelly
Or any of these
She uses Vaseline
Vaseline
Vaseline
I know a guy who goes to shows
When he's at home and he blows his nose
He don't use tissues or his sleeve
He don't use napkins or any of these
He uses magazines
Magazines [Repeat: x4]
I know a girl who reminds me of Cher
(reminds me of Cher)
She's always changing
(she's always changing)
The color of her hair
(color of her hair)
She don't use nothing
That ya buy at the store
She likes her hair to be real orange
She uses tangerines
Tangerines [Repeat: 5]

Re: Silicon spray as a protection film
Yes. The casting is porous and air seeps through. Actually the same happens with tires, but the pores in the rubber are much smaller. The CO2 and O2 tend to seep through the rubber, but the N stays behind. So with every top-up, the % N in the tires increases. No need to pay for special Nitrogen filling.

10^-8 Bar. So that is 0.000 000 08 Bar or 0.008 Pa (N/m2). Would be somewhat difficult to measure down there.
Air does seep through various materials at those levels, depending on thickness and quality. On the metals, it mostly seeps through flaws or voids in the material. Rubber O-rings are a different matter. The interesting part is finding these leaks.
