Is wrapping a bacon sandwich in foil the best way to keep it hot?

AI Thread Summary
Wrapping a bacon sandwich in aluminum foil may not be the best method for keeping it hot, as metal conducts heat and can lead to heat loss. Using a Tupperware container, which is an insulator, could help retain heat better. A combined approach of placing the sandwich in Tupperware and then wrapping it in foil could optimize heat retention by reflecting heat back. Additionally, ensuring the shiny side of the foil faces inward can enhance insulation. Ultimately, the discussion highlights the effectiveness of different materials in maintaining the temperature of food.

Ok, so I was late for work today (as usual), and I had my bacon sandwich in my pocket so that I could eat it when I got there. Anyway, I had wrapped it up in aluminium foil and as I was walking down the road, I thought to myself "was there a better way?".

The way I saw it was that metal conducts heat right, so if had a hot bacon butty, then much of the heat would be transferred to the metal and then lost radiated into the surroundings. However if I had my sandwich in a Tupperware container that is an insulator, then the heat would remain in the vicinity of the sandwich. Am I right? If not, which is better for containing a hot substance?

Put the sandwich in the Tupperware, and then wrap that with foil to reflect the heat back to the sandwich. The best of both worlds.
 
If you remembered to wrap the foil with the shiny side going inside, you'd be okay for a while.

I can only imagine the surprised look on the face of that hot chick in your workplace who asked you "Is that a bacon sandwich in your pocket or are you just happy to see me?" and you said "bacon sandwich, baby !"

Unfortunately I never got to use that line. I am a manager so I had to be in an hour before anyone else was there. Otherwise I would have gladly used the bacon roll to stimulate innuendo filled conversation. :approve:
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
