Trick or Treat — Gone Batty!
By Jeffrey Bishop
Call it a craft, call it an experiment, call it a rainy-day-afternoon-filler or a hands-on classroom science lesson.
Or for Halloween this year, you might want to call it a treat for your visiting trick-or-treaters!
As a bonus treat for door-knocking Halloween cosplayers, consider printing a stack of these Center of Gravity Wing Templates to hand out along with — or instead of — the sugary prizes. Just send the PDF file to your favorite quick-print shop and have them run you off a stack of 100 on orange cardstock for your visiting ghouls and goblins!
