We decided to take a previous project and modify it for this project. Never ending uses for tripods.

I had been thinking about solar cookers when I found this small picture of a parabola form. Seemed unusable at first. So using a image viewer, I enlarged the picture and then printed out. After that I then cut around the splines with scissors. I taped it up. A parabola it is.

Then comes the fun part. I printed out a second form and then glued aluminium foil to the form. Let that dry. then used the scissors to cut around the form again. Looking more interesting. Then I taped up the spines together to get an aluminium foil parabola. Now I am working on an even larger version. Awsome!
