Unrolling Aluminum for the First Time

I was a little nervous about how much energy was stored up in a roll of aluminum from everything I read online.  Today I decided to cut the tape and see what happens.  Here is a quick video of that process in case anyone else is nervous too.

This roll had one sheet of .020 and one sheet of .040 6061 in it.  Both rolls are 4ft by 12 ft.

I'm going to make some mylar templates today and rough cut the shapes of the spar web, ribs and bulkheads.  I'm building in a one car garage, so i need to get the 4x12 sheet down to manageable sized parts, but I need the .040 for the spar web.  Heading on a cruise tomorrow, so no building this weekend (first world problems, I guess!).
