Provide 2 examples of real life objects that incorprate parabolic shapes?

The dish antenna used for satellite communication.  The parabolic shape focuses the incoming signal onto a single point where it can be detected, amplified, and routed to the end user.\n\nA magnifying makeup mirror.  The shape causes light rays reflected off your face to strike the mirror and reflect off that mirror at a slightly different angle.  That particular reflection will strike your eyes in such a way as to make your face seem larger.  The larger it appears the easier it is to determine precisely where to apply makeup.  In addition, it can free a person from needing glasses to apply makeup, thus removing an obstruction to applying that makeup.

build them yourself with a program like the GIMP or Jasc. it aint that hard... or you can get some off of google image search probably.

Try Google or Yahoo.  You'll find worked examples there.  I think it needs diagrams to understand; they and the accompanying explanations are too complex to attempt to reproduce here.

There is a page linked below showing how to make a cell model from a styrofoam ball.

please do not do this for a science project.  too common.  but if you really want to know...most ppl get a small coke bottle and mould clay around it to get the mountain shape.

Here are two (see refs.). Note that the second one is a rotating 3-D model.

How do I animate an inanimate object?

square-ish in shape\ncome in different sizes\nmany varieties

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

They exist, they are just not practical for visualizing 3D geometry.\n\nMost people have trouble with 1st and 3rd angle (2nd and 4th would be front and back "views" given a "side" projection).

2 paralel lines that are not perpendicular to the object they measure

Thinking out of the box:\n\n  Just crumple it up into a paper ball.\n\nRough texture but easily a sphere.

Projectiles without the presence of air pressure creates a parabolic trajectory (path taken by a projectile).\n\n^_^

It all depends on what the shape the object is.

I have been looking - found a pig example (w/ photo) at source 1,\nthen source 2
