Project 6 – “the butt warmer”

Everyone, I’m sure, has seen the posts about the terra cotta pot warmers.  The little “heat your room with a candle’ posts from Face Book to Pin and it and just about anywhere else.  This is not exactly that.  A friend of mine gave it the name James and I have taken to using, the butt warmer!  You see he works in a rather chilly little building where a little extra heat is called for.  He made a heater to go under his chair (a camping chair, so the heat came through) and referred to it as a butt warmer.  James and I decided to experiment with design and waited for the coffee to run out so the can could be used.1.15.15 015

armed with the coffee can as the outside, and inside can and the ‘holder’ can we discussed why the terra cotta was a better option if one had extra or felt it worth the cost to buy new.  Thermal mass and heat absorption was the conversation as holes were punched and a healthy scoop of cold ash was put in the bottom of the coffee can.

James lit the puppy chewed candle and set it in inside.

Just to test how hot it was a little bit f water was put on top.  It took about 4 sec for it to start to boil and sizzle away.
