Acid in a Cup
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.
A man said to a woman to stand under a cup filled with acid that had a piece of paper over the top of it. The woman was not afraid.
How come?
Answer
The acid wouldn't come out, of course! The cup was never turned upside down.

| 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 ;-) |

| 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. |

| 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. |

| 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. |

| 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? Or, Wouldn't she be scared that someone would turn the cup over? |
