The Portable Airlock is a plastic sphere 2.5 meters in diameter. It has 2 manually fully-sealable openings on opposite sides as well as pressurisation holes on either sides. To go into vacuum, one simply steps into the airlock from the pressurized side, seals his door, and opens the outer hole until all air is gone. The door should be closed afterwards. Holes can be opened from either side of each door, and a strenghtened hoop makes sure the bubble doesn't collapse and goes straight into the outer opening, breaking the seal.
