The shampoo prank

So I’m going to put some dish soap and toothpaste in my sister shampoo bottle and I guess I’m just going to see how he reacts and now I’m back my brother just got it just got it and he messed me up she was really mad she didn’t notice until she tried her hair and it got old frizzy and weird and now they have to go to the hair salon because they can’t get any of it out so I think I’m the worst sister ever to my other sister and she’s really pissed off at me
