I read many threads where people talk about making the cookie tin water heater for the winter. Seems everyone advises buying the parts from the home improvement stores or Walmart............ But you can get all the parts you need for only a couple dollars at GOODWILL!!!!!! They always have cookie tins for under $1 and you can find the cheapest lamp they sell and gut it for the parts!!!!!!!!!!! Please spread the word and help your fellow BYC members save a few bucks. Here's one I made this spring that I will use this winter.
