Things we learnt after watching the new Veritasium, in which Derek uses a water jetpack to give us a fantastic physics lesson:
→ When space shuttles lift off exhaust gases exit the nozzle at 3 to 4 km/s.
→ You would need about two million fire extinguishers to create thrust equivalent to 30,000,000 newtons.
→ The orbital velocity of a space shuttle is 28,000 km/h.
