Thank you, 3M!

3M Ear Plug WORKS! It even distribute the pressue inside the ear when the plane landing. My watch told me we are 2000 m above groud, i know it's only because the cabin is 'pressurized'. So we can still breeze easily. 2000 is all right, considering Canberra is 1000m all year long. Anyhow, just think 3M in ingenius designed the ear plug which reduce the pressure pain that many have had due to plain landing.
