Behold the magnificent twelve-card star, a stellar explosion of geometry in three dimensions. Created by Professor George W. Hart, co-founder of the Museum of Mathematics in New York City. Included in this DIY Kit is a reusable stencil to cut the cards with an X-ACTO Knife as well as enough cards to build your own 5.5" card star. Not just a fun activity but also a thought-provoking sculpture to display on your coffee table or hang from your ceiling.
