Make a solar cell in your kitchen from doughnuts

Science

Titanium oxide (TiO2) not only makes sugar coatings on doughnuts powdery white, it also has good photovoltaic properties. Grad students from the University of Notre Dame show how you can use coffee filters, a very hot oven, and a tablespoon of vodka to extract the TiO2 from a doughnut. Add a few bags of Tazo Passion tea, two glass slides, a pencil, and the powdered-doughnut solar cell is ready to be tested in the sunlight and thus proving that there's more than one way to get energy from a doughnut.
