Energy

You might be surprised at how much energy there is stored in a greasy old pizza box. I was a bit cold this morning, so I lit up the stove. I didn't use any wood, rather I just lit the mass of junk mail packed into the stove. Junk mail does burn very hot, but I was astounded to see the stove pipe glowing red all the way up to where it joins the wall from the heat put out by one pizza box. I dread to think what the actual pizza might have done. Or what it likely did to my innards.
