How do toilets flush?

How do toilets flush?  Any guy will tell you that flushing is optional that is what the great outdoors is for.  Now any woman will tell you that going outside to pee in the middle of Winter is not a pleasant experience, especially without an outhouse.  So early this morning as I was outside with the dogs "watering the lawn" I was then instructed to fetch the holy water to flush the toilet.  I went out to the shed and gathered up two five gallon buckets and went to the back creek and filled one full and the other half full.  Lugged them inside the house and placed them inside the tub.  Now we have four toilet flushes ready to go.  They (the women) have already used two flushes.  Hopefully, (the plan is to) have the water line redug and all new line placed in the orchard today.  So when I show up from work tomorrow the water will have magically returned.  Absolutely amazing!!!
