There are things that burn at low temperatures. “White phosphorus is extremely flammable and can spontaneously ignite in air at temperatures above 30°C (86°F). The ignition temperature is higher when the air is dry.” You also can have a mixture of isopropyl alcohol and water that will burn the mixture and not the rag that it is on.
If you are talking about seeing a visible glow from flames, normally you need the flame temperature to be above 500C for you to be able to see it in the daylight (probably depending on how bright the day is). Cold flames, on the other hand, are flames that are visible to the human eye in the dark, and can be very variable in temperature depending on conditions. The cool flame temperature for n-butyl acetate, for example, is listed as 225 °C (437 °F).
It really all depends on what you consider “fire” to be, as whether you are talking about a glow or the actual burning of something. St. Elmo’s Fire is a type of plasma, which is when “the electric field around the affected object causes ionization of the air molecules, producing a faint glow easily visible in low-light conditions.” Note that plasma can be at different temperatures, from the heat of sun or stars to the partially ionized plasmas of neon signs or lightning.
Yeah, I appreciate Todd’s enthusiasm here but I personally feel until there’s a 12 foot privacy fence around the farm it isn’t *that* isolated. It’ll take one person going for a cruise to see them doing echo stuff and then there’ll be rumors.
This is a farm. Lots of land. It’s not like a quarter acre residential lot, like where grandma and grandpa live. It has several tens of acres. Maybe several hundreds of acres. And unless somebody is “out taking a cruise” on the farm – trespassing – they’re not going to see anything.
Something has to be burning to practice with.
Not putting out, pulling out. Like before, when she was showing Selkie that she could pull the fire from her eyes.
When something is described as “fire”, it should probably be assumed to burn.
St. Elmo begs to disagree!

So there is ACTUAL fire that doesn’t burn, not just something described as fire (Elmo’s). Cool.
The Milo assumption is still right, of course. Fire alarms rely on it!
Maybe we should start with the practices on what to do when the fire burns the wrong thing.
I feel like that’s going to stay relevant a very long time.

People are going to get suspicious if an ordinary farm has a 12-foot privacy fence.

if th’en is still around i wonder how they will react to the girls new “trick”
