What should i use to make the reflector? Anything around the house that would work?
You could use foil, metal screen, hardware cloth (that's the 1/4-inch mesh), or even a dissected Pringles can.
BTW, have a look at Ikarus' other parabolic template, which includes a template for the parabolic center and the reflector: »Hey Guys... You'll like this
All you would need for that would be some heavy paper stock, (such as card stock), some foil and airplane glue.
