Fire!

How to get the room temperature from 17°C to 22°C in only 15 min?

The challenge: a table fire or a bio ethanol chimney.
The problem: the table fires sell for around 80,- a piece.
Chimneys start at 200 and the cheap ones are not recommended.
The solution: two do-it-yourself table fires to heat up the room.

I spend almost an hour fighting my way to the local "muy mucho" (a kind of local "nanu nana" for the Germans among you). There I got two big glass jars, white sand, rose and purple coloured stones and some purple paper grass for decoration. At home I assembled the decoration around a cut fanta can and a corn can within the two glass jars.
Put some alcohol (of 96 or 98 saturation) from the local farmacy inside the cans.
Light the fire.
Enjoy the room warming up.This is the big fire, with a corn can as the fuel container.

And this is the smaller one.
You will need between 300 and 500 ml to warm a 20sqm room by 5 degrees with these two fires ;-)
AND it looks good.
For safety: the fires consume quite some oxygen, so check that your windows are as inefficient as ours when it comes to keeping fresh air outside.
