Polycarbonate(PC, Not Personal Computer), the typical Engineering Plastic has been used in our living lifes, from human baby feed bottle, drinking Sports Bottle and daily potable water container in Water Purifiers, Star Bucks Coffe Pots, Head Lights of Automobiles, Street Light Covers(Globe), Sign Boards in Gas Stations, Shops, Stores, Banks, and Lotteries, as well as Sunglasses and Helmet for Astraunaut of Spacemen, from Mr. Amstrong.

Nobody until now recognized, except NASA and some other few human beings that Polycarbonate Plastic can contain Pressure inside, like your cigarette lighters in Pet Plastic, with much thinner thickness than PE, PS or even PET.

Can you imagine that I, Zephyr Archangel replaced the Heaven's Main Entrance Gate with Polycarbonate, just before my birth as human being on June 2nd, 1950(Lunar Calendar) in Ugly Korea during Korean War in Seoul, South Korea.

Now when you are going to fly to Heaven in some years, then you can not avoid encountering me, Zephyr Archangel, who keeps the Heaven's Main Entrance Gate
as Gate Jockey.

Have a good and amazing day!!! with Blesssing from Zephyr Archangel.....
