You could also try the following:
Buy a new knife for Rosh Hashana. After you use it once, burn it within 24 hours. Take the ashes, mix them with chai rotel, and then shmear the whole mess onto your sister’s hair. Make sure to have the proper kavanas as she is yelling at you, otherwise it won’t work. (Due to the nature of this forum, I can not elaborate exactly on what those kavanas are.)Then eat an etrog,regurgitate it, and when it comes out, gather that into an opaque bag. Then, exactly 5 nights later, cut the hair of your sister where the shmear had been. Take the hair and put it into the bag with the etrog, and shake hard at 350 degrees. Let it fester for some time with fruit flies. Afterwards, wait precisely 18 days, 18 hours, 18 minutes, and 18 seconds, and begin to drink the whole mixture, making sure the whole procedure lasts exactly 72 minutes.
That should work.
