Do you like butter? There are a couple of ways to test for this! With buttercups, you should hold it under someone's chin, and if you see a golden glow then it means they love butter!
Or, rub a yellow flower under someone's chin and if it leaves a yellow spot, then that means they love butter! You may use buttercups or yellow dandelions or any yellow flower for this version of the experiment. +++ Artist is Rosie oNeill who created the Kewpies
