Tires Checking air in rear tires

[tony3542]

When checking my rear tires unscrewed cap ,valve core came off with cap,fluid shot out about 10-12 ft.I was lucky it missed my face and eyes,should have been wearing safety goggles.
I've still got to check my air.Thought about stopping tire at top center jacking it up to take pressure off and trying to unscrew it?Any ideas?
Thanks,

My tires a slimed. I just park a TDC, wait for slime to go down and then gently press to see if any slime comes out. Then I just check. If the valve core came out, that is an entirely different issue.
