Useful idea for rotationally shaping foam (or kebabs :-) ).

    http://www.vatsaas.org/rtv/arsenal/bradrocs/napkin/napkinrocket.aspx

May have applications in other areas for shaping foam and similar objects.
Original idea from a Lebanese Shawarma shaper.

Somebody from the Water Rocket list pointed out this link.
Their application was nosecone shaping and the original application was  the
body of "The Happy Birthday Party Napkin Rocket of the Apocalypse" flying on
a K550 motor (!).
