Penny Flyer (NOT! for CO2 laser cutters!)

Update! Warning! Not for CO2 Laser cutters! The foam is made of a version of VINYL which is deadly to lasers. R.I.P. my first laser tube. ;-(

A simple 9-inch flyer made out of craft foam and pennies in the ring for heft.
Fast to cut, easy to assemble, and incredibly fun to play with.
I have a video, but 3GP is not supported, sorry.
