Subject: Re: Conic Sections - sliced model
Take a large loop, (we have old(?) toys called hulla hoops) and mount it so it can turn on a vertical axis that is also a diameter. You could just hang it by a string. The circle will turn into an ellipse as it turns. 3 to 5 rpm will work well.
Those who can, do.
Those who understand, teach.

g for a real physical large scale demo of Conic Sections. It means
a Circle, Parabola, Ellipse and Hyperbola.
I prefer to buy such a model or you might have any suggestion.
