Which is hotter, the red coals at the bottom of the campfire or the blue flame glowing around the logs?
What do they do with cow brains? Do they go in hot dogs? What about other internal organs? Is the entire cow used up?
Is it true that there is a layer about 2 kilometers up where various insects float on silk balloons? I’m not joking! For example, spiders make balloon webs and float about for awhile. Apparently the nighthawk it adapted to feeding at this altitude. I went on an interpretive walk and this is what the guide told us.
This sounded sufficiently weird that I needed to check it out on the SD.
You go camping with cows?! I usually just bring ground beef (saves me loads of time)
Currently, most countries are banning the use of bovine spinal tissue and brain from food meant for human or animal consumption. It is one of the measures used to control Bovine Spongiform Encephalopathy (BSE or Mad Cow Disease).
Now, there are always places where you can get spinal column and brain if you really want to, but those aren’t legal. Not in the US anyway.
The rest of the cow does go for various foodstuffs, particularly processed food like luncheon meat, or to feed other animals. That’s how where all that beef protein in the dog chow came from. In fact, even the blood, hair, and hooves are used to make things, though not always food.
A lot of professors I had in college loved to go on and on about our wasteful society and how past tribal societies were awesome for eating all parts of the animal. These same professors never bothered to walk across campus to the Animal Science side and find out that we do use all parts of the animal (whenever safe), we just figured out better ways to do it than choking it down.

This page would seem to suggest that the coals (charcoal) at the bottom are much hotter than the flames.
Wait… did you say blue flames? Is this a natural gas-fired campfire? Blue’s not really a normal color for a wood fire.
I’ve never, not once, seen red coals. I’ve seen orange coals and yellow coals and white coals (each one hotter than the last) and all of them are hotter than flame. From a wood fire. But I’ve rarely seen blue flame from a wood fire, either. Occasionally the top licks will be blue - those are even cooler than the invisible, white, yellow or orange flames (each one cooler than the last) you usually get from wood.
Descriptive thread titles would really help.

I merged all three questions into one thread.
Please don’t open separate threads for questions about the same subject.

If you have blue flames, they’re probably hotter than the coals. But the coals will have more heat in them. Heat is an amount of energy, while temperature is (approximately) energy per particle. Since flames are so tenuous, you get a lot more particles in the coals than in the flames, so even though each one has less energy, there’s more total.
Rico, if I may ask, how are these the same subject?
The thread titles were Camping Question #1, Camping Question #2, Camping Question #3, all by the same OP. I felt they could be handled all in the same thread.
If you’re wrong, question #3 will never be answered.
We’ll have to send it to Cecil then.
There is a sort of “aerial plankton” made up of very tiny insects that virtually float about becuase they are so light. Juvenile spiders disperse by “ballooning,” sending out thin strands of silk that are caught by the wind, and can also get quite high up. However, while nighthawks do fly around catching insects in the air, I am not aware that they regularly forage that high (though they might). I regularly here and see them flying around maybe a few hundred feet up.
I understand what question #1 has to do with camping, and #3 was apparently inspired by an interpretive walk. But I am wondering what cow brains has to do with it, unless the OP happened to hit one with his Winnebago.
OK, the coals are orange. There are blue flames licking around the wood. I know with natural gas that blue is the hottest flame. With wood, I am not so sure.
I blew this. I just returned from a camping trip and had three questions in mind. I was looking for some light summer humour but instead I got confusion. :smack:
Roasting hot dogs over a campfire.
