Mirroring a parabolic dish

Yes it is Science Fair time once again and this year Pappa and I are doing solar power with reflected sunlight. In this video I show how I stick the reflective tape on to our parabolic dish. I also talk about how this parabolic reflector works and why we don't need those pesky bubbles.

First we had to prepare the dish by sanding it out so it was smooth and down to almost bare metal. Then we painted it glossy black to help with the reflection.
