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.
Sent by Kathleen. Editor: This romantic, old-fashioned way of making iced tea is very popular in the summertime. You just place a few tea bags in a big jar of water and let them slowly steep in the hot sun. And technically, yes, this method is not strictly safe. Our reading shows that the 130Â°F or so that the water reaches is an ideal temperature for harboring (and growing) the bacteria commonly found in tap water. Without a boiling session to kill off this bacteria, there is the chance that they will grow in the sun tea.
