Most of the fuel on-board a rocket is used in the first few minutes of the mission to achieve an escape velocity of at least 25,000 mph (7 miles per second or 40,000 km/h)âthe speed a rocket must theoretically attain to escape Earth's gravity.
Traditionally Japanese green teas and spring teas are brewed at lower temperatures (160Â°F to 170Â°F) and standard Chinese green teas at higher temperatures (170Â°F to 180Â°F). Pre-warm the teapot or cup (optional): Pour a small amount of boiling water into the pot or cup. When the pot or cup is warm, pour out the water.
Depending of the variety of green tea it should be brewed around 175 degrees F (79 C) give or take 5 degrees. This can vary on the variety so be sure to check that carefully. You started off with old green tea. Green tea, when properly packaged, has a shelf life of about 6 months. Once opened you have about 2 months to use it. That's for properly packaged (vacuum packed or nitrogen packaged) tea. If your green tea wasn't packaged properly and is exposed to any amount of air, it probably was never good to begin with.
