How to get alc?

I need to bring like 2-3 shots for a party and I can’t get alcohol I’m broke. I was gonna get some from my parents since they’ve got some whiskey. My friends could probably just ask their parents and they’d give it but my parents are STRICT. So if I take just 1/4 or 1/3 of the bottle is there any way I could like make it seem like the alcohol didn’t disappear. It sounds like such a non problem but my parents are horribly strict and religious.
