The cup was filled with orange juice!
that was not a very good one man, maybe next time
I'd still be scared.
EXTREMELY EASY!!!
that was REALLY EASY!!!!!
I never would have thought of that! Very, very good teaser!
Sorry, Sunny, but what teases me is Why does She has to be afraid?. I thought there was a risk of the acid being spilled, but never of the piece of paper holding the acid. :-S
OK. Have fun and we'll wait for the real hard ones to come ;-)

acid would burn THROUGH the cup.
I'm with puzzled.
I'd still be scared... acid burns... I knew that it was right-side up... could've been harder
I'm with Liz and COMP. Acid burns through. The strongest acid is in our stomach-Ph 1. VERY strong. I've read somewhere it would burn a hole right through a hankie!
Good riddle though.
Good riddle though.
i was confused but only because I never thought of the cup turning over at all.
I suppose it would depend what kind of cup was holding the acid as to whether it would indeed burn a hole through, and if it would, the type of cup would determine how long it would take for it to happen, so the woman could stand there for that amount of time before the cup actually began to be eaten away. Didn't like this one at all.
I agree...too many options to satisfy the correct answer...I mean the answer that was given.
good teaser alot of different answers to it though
Good concept, could have been more "tricky" if it was stated that the paper was the only thing that could keep the acid in the cup, to scare you more too.
Wouldn't Acid Go Through The Cup?
OMG. The answer is SOO obvious that I got it wrong. And yes, acid would burn through the cup, unless it was made of some materials that wouldn't let it. If there is any material like that.
I feel sorry for the authors parents
Not all acid would go through the cup...lemon juice (citric acid) or vinegar (acetic acid) are both relatively weak acids.
Good teaser. I like easy ones sometimes!

Of course acid wouldn't go through the cup... it wasn't a paper cup. In fact it wasn't specified. Could have been a tin or glass cup. The type of acid wasn't specified either... could have been a very mild acid as was suggested in several other comments.
Not my favorite teaser... sorry. It just didn't have any challenge at all to it.

I thought the answer was that the acid was citrus fruit, orange juice, vinegar, etc.
wouldn't the acid burn through the cup? and why would she stand under it in the first place?? i agree with puzzler though. keep emcomin!
Wouldn't the acid burn through the cup? Or, Wouldn't she be scared that someone would turn the cup over?
How about this?: The woman was not afraid because she refused to do what the man told/asked her to do (i.e. stand under the cup).
