Stage 8: Magnetic Tap
The water flows through a magnetic tap as it gets dispensed from the unit. "Magnetized water is claimed to be energy-building, activating, cleansing and detoxifying. There are reports of people resolving bladder problems, recovering quickly from a stroke, alleviating arthritis pain and reducing blood pressure by drinking magnetized water."
Mmmm, sure. Way too much bullshit being slung there....
