I have a pale pink bottle with a liquid inside. How can I figure out what it is? I think it is shampoo or soap, or maybe even lotion. I found it in my closet. I think it's homemade. I won't put it on my hair, but I will taste it for testing purposes.

please help me to not starve

happy scrappy — Mon, 31 Aug 2009 07:54:22 -0800

I'm having surgery in my pelvic/abdominal area on Friday, and since my doctor is expecting some bowel involvement, he is putting me on a clear fluid diet as of Thursday morning. I'm going to be STARVING by surgery time (noon Friday). I feel weak and irritable if I miss one meal, let alone a whole day and a half. At the pre-admission clinic, they told me I can have black tea/coffee, clear soda, Jell-O, water (of course) and "consomme" (broth or bullion, I'm guessing).

Any ideas as to what I should / should not consume that would help to alleviate my hunger? I'm also taking several drugs for pain, which I prefer to take with food, as they tend to upset my stomach a bit.

Any ideas/advice would help. I realize I should have brought this up with the nurse, but it didn't occur to me until now, with this fasting day looming closer (I know it's only a day and a half and I'm being a big suck, but I'm really dreading it). I will be able to talk with my doctor tomorrow, so any advice you give can be run by him first (he may or may not have any helpful ideas, but he'll tell me what I can't have).

Thanks in advance!

Would you drown in a pool filled with honey? More generally, which liquids are swimmable and which would lead you to your doom?

Pumping water with batteries

kamelhoecker — Thu, 02 Jul 2009 07:45:22 -0800

Small pump. For liquids. Battery powered. Inexpensive. Does such a thing exist? I've been searching for pumps and haven't found much available. I've found several pumps for garden fountains, that are basically a small paddlewheel on a fast motor that flicks water. Far too inefficient for battery power.

I've found homebrewers making their own peristaltic pumps which could be shunk down.

Any other simple homemade pump designs or sources for cheap pumps?

Liquid Plummer or Drano?

redandblue — Tue, 02 Jun 2009 08:56:14 -0800

Liquid Plummer or Drano? I'm never satisfied with either. But really, which one is better? I have a clog in the bathtub probably from hair. I tried digging as much as I could out and it is still not draining.
I would appreciate personal experiences that would help me decide with item to purchase.
This must be something I can purchase at the grocery store tonight.

What is a gel that turns to liquid with minor agitation?

Bugbread — Sat, 30 May 2009 02:48:16 -0800

What do you call a gel that turns into a liquid with very minor agitation/pressure? I have an alcohol hand cleanser which, when you push the pump, comes out like a gel (like thick shampoo or the like), but when you start rubbing your hands together, turns into a regular fluid, like straight alcohol. I remember seeing something on a science show on TV which talked about this type of gel, which had a special name. What was that name?

(Note: telling you the name of the hand cleanser probably wouldn't help, as it's Japanese)

Looking for a way to keep 2 spoonfuls of medicine in my pocket.

Anonymous — Wed, 06 May 2009 14:29:11 -0800

I'm looking for a clever way to bring 2 tablespoons of liquid medicine around with me in my pocket on weekends, without lugging around an entire bottle. I take a medicine twice a day - once around 10:45am, another around 4pm. It is one tablespoon of a medicine per dose, and it does not come in any alternative form. Taking this isn't a problem at work, as I have a bottle that sits in my desk. However, I find myself missing it on weekends when it is inconvenient to take a whole bottle around, plus a spoon. Any thoughts on how to conveniently take around 2 tablespoons of a liquid a day (hopefully something that can fit easily in a pocket and not leak).

Asked anon because I don't want to worry friends and others who don't know I am taking meds, but read MeFi and know my user name.

Where to obtain a small amount of liquid nitrogen in north Seattle?

Riemann — Mon, 04 May 2009 11:51:10 -0800

Where to obtain a small amount of liquid nitrogen in north Seattle? First off, yes I am aware that this stuff can be extremely dangerous if not handled properly. And no this is not going to be used for anything illegal or blatently stupid.

That said, I need a small amount (preferably less than a liter) of liquid nitrogen. It would be great if I could pick it up in north Seattle (U-District for preference). I do not have any university or student access.

Anyone know if this is possible? And if so, roughly how much it will cost?

Get coffee out of a Macbook keyboard?

Orb2069 — Wed, 15 Apr 2009 13:56:20 -0800

Just spilled coffee into a 13" macbook. Remediation tips? Splenda and cream, no sugar. Any ideas on stuff that can be done to mitigate the damage while it's still wet?

What is a dense/heavy transparant oil or inert/safe non-water-based liquid?

-harlequin- — Fri, 18 Jul 2008 16:28:15 -0800

I need a crystal-clear transparent liquid that is as heavy (dense) or heavier than water, not dangerous, and not difficult to obtain. The heavier the better. The catch - it can't be water-based. I'm trying to suspend (or at least swirl) a non-soluble coloured powder in a liquid as part of a gift, but I can't use water as this will react with and ruin the powder over time. Oils preserve the powder nicely, but the density of the two that I've tried (baby oil, and liquid paraffin) is too low - they are too light to float the powder for very long and so it settles to the bottom fairly quickly. I can't choose a lighter or more durable powder either, so I'm looking for a heavier liquid.

This list of the density of 150 liquids helps a little, but I don't recognize (by chemical name) most of the liquids, even though some I might already have around the house, so I was wondering if you have any insights.

As with water, reactive chemicals like acid will ruin the powder. (Also, acids are a too much of an irritant/danger to want to put into a gift)

I'm hoping for something I could buy at the local department store or hardware store. I don't really want to order something from a specialist or chemical supplier.

Realistically, I suspect my best bet is a heavy but transparent oil, so it probably won't even be as dense as water, but at least something denser than baby oil. Any idea what that might be?

And if you were wondering, it turns out that paraffin floats on baby oil :-)

Water Sucks

It seems obvious, but what is the best liquid to drink to prevent dehydration in a desert environment? My father is a stubborn old coot. He does not like water, never has, never will. He isn't about to change in his eighties either. Last summer we went on a vacation to Grand Canyon West. We did all the touristy stuff, walked the Skywalk, rafted the Colorado River, and hiked the canyon rim.

One of the days there, Dad showed all the outward signs of dehydration. Air temperature was well above 100 with single digit humidity, typical Arizona desert summer conditions. All he would drink was his favorite Diet Coke. We told him he was looking dehydrated and needed to guzzle water. He said Diet Coke is mostly water, it has no sugar, it would be perfectly fine for hydration.

To shorten the story, we eventually got him to drink water and everything turned out fine. But the question has remained. Intuitively, it would seem that Diet Coke or some other soda would not be the best solution for desert hydration. Why not, and what are the best fluids to drink when in that situation?

I seek the King of Nutrition Drinks

StrikeTheViol — Sat, 06 Oct 2007 14:06:55 -0800

LiquidNutritionfilter: I know a little about sports nutrition, and a little about parenteral nutrition. Is there a nutritionally complete liquid that healthy people can drink such that the only other necessary is water? If not, what liquid comes closest to being The One Food? If it's not commercially available, what's the closest to it you can buy? Not planning on this myself, just curious about the latest advances in liquid nutrition science.

If you're dumb and you know it, clap your hands.

I'm sure this has been covered before but I'm in a small panic, so forgive the indulgence. I just spilled a small (maybe 1/4 oz.) of beer on my MacBookPro. I caught it very quickly and sopped up the liquid with an absorbent towel. However, a small discolored spot has developed in the LCD and I'm wondering what the best way to abate the liquid might be. So, I'm stupid and sat a beer down too close to my laptop (a 15" MBP) and knocked it over a short time later. I caught it very quickly, but a tiny amount of beer landed on the computer near the upper-left hinge at the joint between the screen and the body of the machine. As I type this, there's now a small bright spot in the lower left of the LCD if I view from the right angle... It's as if the surface tension of the liquid drew it between layers of the LCD between the pixels and the backlight, perhaps? It actually looks as if it's drying, but I'm hoping some Genius can tell me the best way to abate said stupid damage to my bread-and-butter machine. tyvm in advance for your help.

Does stirring accelerate cooling?

flyingcowofdoom — Tue, 09 Jan 2007 13:10:11 -0800

Does stirring a mug of hot liquid make it cool faster? Let's say I have a nice, hot mug of coffee. It's too hot to drink at the moment because I got it from McDonald's. Would stirring the coffee with a spoon make it cool down faster? I'm just talking about a gentle stir. I think that stirring it fast enough to create a vortex would accelerate cooling because the surface area of the liquid would increase, but I can't decide if a gentle stir would affect the cooling process. What do you think?

Not planning to try this, just curious

Has anyone taken ice through airport security? It's a solid, of course, but I wonder (idly) what the reaction would be.

Mars Needs Protein!

Servo5678 — Tue, 19 Apr 2005 15:35:08 -0800

I'm going to be on an all-liquid diet for an undetermined amount of time in order to give my diseased and angry intestines a break. What are some good sources of protein that can be taken in liquid form? Here's the catch: due to my medical condition (ten years with Crohn's Disease) I am on a very restricted diet. I cannot digest any of the following: dairy products (including lactose and whey), fruits, vegetables, nuts, highly acidic drinks, caffeine, coffee, chocolate, alcohol, and a bunch of other minor things.

My liquid diet consists of water, cranberry juice, vanilla Equate (Wal-Mart's non-dairy Ensure), caffeine-free flat Coca-Cola, original green Gatorade, and sucking on hard candies until they dissolve. I take a ton of vitamins everyday as well as B12 injections. I need a source of protein in order to keep up with my daily life. Can anyone recommend such a thing that does not include ingredients from the restricted list?

How do I ship carbonated bevvies overseas?

small_ruminant — Wed, 26 May 2004 16:16:41 -0800

What is the best way to ship carbonated beverages overseas? (In this case it's rootbeer from California to Australia.) Will they explode with the pressure changes?

Can someone explain the red liquid spray patterns that appear on the asphalt of Southern California freeways?

quarantine — Fri, 26 Mar 2004 19:48:33 -0800

Can someone explain the red liquid spray patterns that appear on the asphalt of Southern California freeways? [more inside] A few times a year, I will come across a delta-shaped liquid dispersal pattern on Southern California freeways, usually on the 101 through the San Fernando Valley. The delta expands in the direction traffic flows, starting at a point-ish place and fanning outwards. It's what you might expect to see if you dropped a can of paint off the back of a truck at speed. But if it is "paint off a truck", why is it only red (if there is not selective memory involved here); why not other colors? Pure chance?

Of course, the first thing my mind jumps to is "blood", but the arguments against it being donorcycle street pizzas are [a] I don't think blood would stay that deeply red and [b] I don't think it would be that tenacious on asphalt. But I really don't know what I'm talking about, as my only experience with blood pools is that bastion of scientific integrity CSI (and yes, that's something you'd need a TV to get. :)

I'm usually pretty good at online research, but I don't even know where to start on this one (many of my guesses, not even using the word blood, take me to horror fiction or death fetishism.

Completely unrelatedly, would a U.S. resident here like a free, sealed packet of heirloom flowering tobacco seeds from Seed Savers Exchange? It was included by accident in my recent shipment of seeds, SSE doesn't want them back, I'm surely not going to grow them, and I'd experience more than $0.37 worth of guilt throwing them away. I don't want your address or anything, I'll send to a POB, PMB, your employer, a maildrop, whatever.
