If you didn’t know any better, you might think it’s magic. David Garcia gave TechCrunch a demo video demonstration of a device developed by his company, YPlasma. A row of five candles sit in front of a harmonica-like device with wires hanging off it. Suddenly, the flames flicker and then snuff out. Inside the device, two strips of copper coursing with electrical current are generating plasmas, or clouds of charged particles, that induce airflow through the cavity and out over the candles. It’
