When I think of a traingular prism, my first thought is of a Toblarone chocolate bar! It was the first item I ever remember being packaged as a prism. My dad would bring one into math class when we first started studying this shape. And it is still as good today as it was way back when, for a child to see how this shape is constructed. If you open up the packaging, you have an instant triangular prism net!
