Some observations the students made.
The Taco-Bell clip looks like the bottom of the bell is an ellipse, whereas the top part looked like a parabola. There were some arches that looked like a semi-ellipse.
Someone pointed out the circle that is the steering wheel and the tires on cars.
The tower was a parabolic dish.
McDonald's had two parabolas.
The gas station had an elliptical sign.
There was a big argument about the wires on the sidewalk. The only thing it was not called was circular.
The stone arrangement looked like a semi-circle. Since the video is from an angle it almost looks like an semi-ellipse.
The bridge had some discussion as well between a hyperbola and a parabola.
The last clip was simply a nuclear plant shaped like a hyperbola.
Most of all, it created some great MATH discussions. Give it a try.

That reminds me of an assignment I used to give. They had to take pictures of conic sections THEY found in the world around them. I loved seeing pictures of them swinging, at McDonalds, etc. That was before flip cams so they were still shots, but they were always surprised at the places they found them.
