Examples of parabola's

I'm trying to find a few (real-life) examples of parabola's, and so far I've only found one:( A bridge: the top bit can be a parabola.

Can anyone else supply me with a few more? Cheers!:)

The inside of car headlights are shaped as parabolas because if you stick a point light source at the focus of the curve, it reflects all the light in the same direction, namely out the front.

comets form parabolas when they are deflected by the gravitational pull of the sun

Rainbow,... The thing girls like to jump with,.. Hot balloon, and it's really hard to say many other things, because a parabola in geometry is only 2D, while things in the reality is mostly in 3D and 4D if you are an SR, GR student.

a projectile (bullet, ball etc)

representations of maximum areas etc


quite a few things..

Thanks!:)

Comets actually follow elliptical orbits so they don't count.

not the whole orbit man, but the bit around the sun & other stars
