Best NEW steel wool experiment. EVER!

The IRON (Fe) in steel wool reacts with the OXYGEN (O2) in the air in a mesmerizing reaction that changes the mass in unexpected ways while the steel wool burns in this weird combustion reaction. Watch and see how steel wool covered heats the air and increases the pressure pushing water out of a jar submerged in water, only to have the water get pushed back in by the atmosphere when the steel wool runs out of oxygen.
