フィッシャー・スペース・ペン
Marketers of the Space Pen claim that the writing implement can be used in zero gravity, upside down, underwater, over wet paper, at any angle, and in extreme temperatures. The pen, which was invented by American industrialist Paul C. Fisher, uses pressurized(気密構造の、加圧された)ink cartridges to force thixotropic(揺変性の)ink through its tungsten carbide ballpoint.
