well turns out that my little brother did drink the juice/onion juice. I had forgotten all about the prank that i was going to pull on my brothers. well when they got home i was on the laptop listening to BAP Warrior. like i said i had forgotten about the juice, they came into my room and they saw the bottle. well they were thirsty and drank it. Thankfuly i looked up just in time to see their reaction. It was the funniest thing in the world. they went running to the restroom and started brushing their teeth. i was laughing my off!!!!!!! I wish you guys could have seen it!^^
