well most, not all, some would be like psssshhhaw whatever. so I'm sure people have tried stranger things and lived to tell about it.
dog tooth paste
baking soda (though that probably doesn't count)
dentrer cleaner (but i thought it might be a mint)
clearasil black head scrub (tasted delightful, i would probably have eaten more if their wasn't that warning to call poison control if ingested, and I don't know if I was panicking or what but I didn't feel well for a few hours, so won't do that again, even though it tastes amazing btw)
don't ask why I do these things, its usually someone asks me to, or in the case of acne wash i was on the toilet bored and i went hmmm i wonder.......
but i can't be the only one.
