# Interesting Question of the Day – 4 January 2017

Here is a picture of nine shots being lined up on an elliptical pool table.

If you rule out problems with spin and friction and other variables, and deal purely with geometry, how many of these nine shots will go in the hole?

The first new player to comment on the website with the correct answer wins a free drink at their next iQ Trivia show.

I reckon it’s a trick and they will all eventually go in.

It’s no trick, but they will all go in.

From one focus, it will always rebound off the side to the other focus.

All of the shots should go in, as both the ball and the hole are at the focal points of the ellipse.

That’s the answer and the explanation.

No friction will carry on forever.

So all of them…

Clever. And also true.

All of them

Every one.
