Science Buddies: "Ask an Expert"

We are trying to do the project involving frying a diode, but have been unable to get the diode to fry. Followed the instructions on the website and purchased the recommended products. Changed the soldering iron (up to 900 degrees) and multimeter. We have even connect the diode to the soldering iron for 30 minutes and it still works. What are we doing wrong and what can be done to make this a successful science project? The project is due on Friday.
