What do get when you put a roll of toilet in a metal can and pour rubbing alcohol over it?

A D.I.Y. Metal Can Heater.

Wow! Now that's another way to beat the frigid winter temperatures.

This D.I.Y. heater would be very handy hunters, out camping or even (teachers) as a great science project.

It would help heat your home on the cheap side too. Rubbing alcohol is what a dollar, toilet paper less than that, and use can use any kind of metal can.

I hope I'm never in situation that would require I need to do this, but it's nice to know anyhow. Just put this in your I might need this someday, but hopefully not file.

Overall, having this knowledge is power.
