will my mom be able to tell i stole some vodka

hey so me and my friends (all under drinking age) all wanted to try vodka and my mom keeps it out in the open and i decided i was going to take some. so when they went to work this morning i took some and filled up my mini gatorade bottle like a little less than halfway and replaced what i took with water. i have a diagram below to show how much was originally in the bottle vs how much i took. will they be able to tell? i don’t think they really take shots straight from it unless they are partying with they’re friends and that’s like not too often. i would say they mostly mix it into things. main problem is, she has a celebration coming up. so they could potentially be pregaming at our house, though i’ve never seen her pregame with straight vodka, it’s always a possibility that may get me found out immediately. on the flip side, she may get super drunk at a bar, and come to our house to continue the party, and not notice that they’re drinking partial water vodka

the red like is where the vodka was filled up to originally, the blue line is approximately how much i took + refilled with water

also don’t tell me i shouldn’t be doing this, i know its stupid but it’s a one time think and me and my friends just want to experiment in a safer way than our first real drinks being at a party or something where things can go wrong.
