Acid in a Swimming Pool
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.
In a crazy game show, contestants have to willingly wade through a swimming pool full of an acidic substance to win points for their team. Five of the contestants decide to go through this acidic substance, and when they get to the other side of the pool, none of them are hurt. How is this possible?
The contestants were wading through lemonade, or a similar acidic substance. Although they're not strong enough to burn your skin, liquids like soda and lemonade are still considered acidic. The contestants were perfectly safe, although some of them wouldn't dare wade through such a sticky substance. This doesn't make the show any less strange, of course.

|So one could say this is a "ci-trick" question. |

|Lol, I said Citric Acid. Well, I guess that's still correct, since lemonade comes from lemons, and lemons have citric acid.|

|Yep, citric acid is in lemonade, and even if it wasn't, it would still be an acceptable answer.|

|I just said "it is not a strong acid, maybe vinegar or something similar". Both lemon juice and vinegar have a Ph of about 2 so I think I was on the right track as well. Not sure which I'd rather we through - sticky lemon juice, or smelly vinegar.|

|Cool teaser. I wonder what show this is? |
By the way, Habs, I'm weird and like the smell of vinegar.

|Lemonade is not technically an acid, it is an acidic substance. Lemonade is usually around 80% water|

|I said acetic acid, thinking it is vinegar...but upon looking it up, vinegar is only 8% acetic acid, and it is strong enough to burn your skin. So yeah. Fail.|

|It would be a good idea to state that the contestants have to wade bare foot, otherwise a trivial answer is that they wear protective waders.|

|Mad-Ade: Nearly all laboratory acids are dissolved in water. A 1M solution of HCl is really nasty stuff if you get any on you, but the concentration is 1 mole of HCl dissolved in 1 liter of water (which is around 55.6 moles of water). So saying that something is mostly water doesn't mean it isn't also a really nasty acid.|

|I guessed something to do with pH|
