Wondering what to do with old CDs? You can heat them in the microwave.
Part 1
Step 1. Take an unwanted or damaged CD or CD-R and place it vertically in the microwave, supported by a glass cup or a paper cup.
Take an unwanted or damaged CD or CD-R and place it vertically in the microwave, supported by a glass cup or a paper cup. Do not use any metal materials for support.
Step 2. Set the microwave for five seconds at maximum power.
Set the microwave for five seconds at maximum power. Close the door tightly and start it.
Step 3. Be ready to turn off the microwave if the disc starts to smoke.
Be ready to turn off the microwave if the disc starts to smoke. Inhaling this smoke is harmful to your health. Ensure good ventilation in the room beforehand, such as opening a window near the microwave, to effectively clear the smoke.
Step 4. Enjoy the spectacle.
Enjoy the spectacle. The heated aluminum on the CD creates tiny electric discharges resembling lightning and sparks. You can watch the action through the microwave door, but take normal precautions.
Step 5. Wait a few seconds before removing the CD.
Wait a few seconds before removing the CD. Even after just five seconds, the disc can conduct electricity. Touching the recently damaged CD with bare hands can burn you. Do not inhale the air from the microwave immediately after the experiment. Allow the microwave to cool down and ventilate the room through an open window.
Step 6. Inspect the layers of the CD.
Inspect the layers of the CD. Notice the various patterns and tracks etched onto the surface, creating small metallic "islands".
Step 7. You're done.
