This is effin cool.  We centrifuged a can of pumpkin to yield a few tablespoons of a clear, orange pumpkin-flavored liquid.  We saturated it with sugar and spiked it with pumpkin pie spice, then heated the mixture to 300F and cast it into hard caramel molds.  Then, we spun the hard caramel in a cotton candy machine to make 2” puffs of pumpkin-flavored cotton candy.  Then, we squeezed the puffs into the shape of a skull and cut out triangles for the eyes and nose.  Finally, we put it on a stand with a candle behind it.  Presenting the pumpkin cotton candy jack-o-lantern, as interpreted by Jet City Gastrophysics. 

Happy Halloween!
