OWN, I will go first then with the explanation.

I say it is a fact and it can be explained by the Coriolis effect and the conservation of angular momentum as explained http://en.wikipedia.org/wiki/Coriolis_effect

It is the same reason why cyclones rotate like they do in different parts of the world.

Based on the answers I see here, I cannot actually award an IT as yet, as no-one actually has the answer correct. :wall: :wall:

Dr Phil, the Coriolis Effect is an excellent try, but actually applies mainly to weather phenomena, like tornadoes.

Anyone else willing to throw in their tuppence-worth? I want to award this question to someone ... :pray: And I'd hate to go with guesswork. :hmz:

OWN, is it not just the Coriolis effect on a smaller scale. Which is basically the conservation of angular momentum?

Thank you for participating Rooies, WFG, Heksie, Dr Phil, Picnic, and - a great welcome to our newest quizzer :dance: :dance: :dance: - Peter Lalin! :clap: :clap: :clap:

Dr Phil, the Coriolus Effect is actually too weak to influence water spinning down a drain. In fact, this question is indeed a MYTH because, as Picnic rightly notes, it is the geometry of the outlet pipe that determines the direction of spin of the water! I always believed this myth as a child, but couldn't get uniformity when letting the water run out of the bath. :wall:

Which means PICNIC is IT. :clap: :clap: :clap:

:lol: It was only a shot in the dark. :whistle:

Black mamba is the longest venomous snake in Africa averaging around 2.5 to 3.2 m (8.2 to 10 ft) in length, and sometimes growing to lengths of 4.45 m (14.6 ft). F or M?

Fact.... :tongue:

I have seen one close to 5m close to the reception in Mopani. It was almost as long as the road is wide. And it was at night :big_eyes:

Picnic it was very scary, At least we had a torch. The people walking behind us didn't have one and I don't even want to think what would have happened if they stepped on that monster.

OK Fact or Myth: If running constitutes that 2 or more feet be off the ground at any given time for a 4 legged animal. Then Elephants can only walk fast, 40km/h fast. As they cannot have 2 feet of the ground at any given time while moving.

I thought about that as well but does 2 feet leave the ground? Now that is something to ponder about... :hmz:
