Act 1 - The Question
  1. How long will it take for the bottle to empty?
  2. Estimates? Low, high, best guess.
Act 2 - Information Gathering
Act 3 - The Reveal
  • Were you on the right track?
  • Can we answer any of your other questions?
  • Where to now? What do you wonder as a result of this investigation? What would be a suitable sequel to follow Act 3?
The Sequel - Where to next?
  • If we had to fill an Olympic-sized swimming pool with the same flow rate, how long would it take?
  • If we wanted to fill an Olympic-sized swimming pool in 3 minutes and 40 seconds using only those bottles, how many bottles would we need?
  • If we had to empty a petrol tanker through the same-sized hole, how long would that take?
  • If we collected water flowing at that rate from a mythical, never-emptying bottle… how much water would we collect in a day? A month? A year? How much would have been collected since you were born?
