Can you really buy or build a solar oven for $5? Yes, you can. My sister hit up the local dollar store and got everything she needed to build a $5 funnel solar oven. If you are on a budget or just want to try something new and fun make yourself a funnel solar oven and have some fun.
Here is my link to the only solar oven I use and recommend: http://bitly.com/BestSolarOven
