it can be anything that demonstrates the properties of physics... but it should be something that i can build, and then use equations and such to study the physics properties. anything BUT a mag-lev train, i already did that

Well, my Hon. Phys. class just built an airplane. We had to calculate everything, like lift, drag, Aspect ratios of the wings, velocity and force vectors, acceleration, the whole enchilada. We even had to do an AutoCAD drawing of everything.

Drop an egg off a roof and time it until it hits the ground. Back-calculate the height of the building you dropped it off from the time it took to hit the gound. Also calculate the speed at which the egg hit the gound and the impact force exerted in stopping it. Then build a little box with the objective of keeping the egg from breaking. You can add a parachute or bubble wrap or any number of things. It would be even better if you built a couple. Drop these off the roof and time them as well. Then calculate the amount of drag they incurred while falling, the speed at which they hit the ground, and the impact force in stopping. Report which eggs broke as well.

I would put together the following: a container that has some type of insulation around it, something like a soda bottle surround by padding, filling it with sand, and connect it to a rope and pulley. Measure the distance that you are about to drop it and the sand's temperature, and then begin to drop it and quickly pull it back up. Determine how many times you have to drop it to equal a fall of 100 meters, etc. Then take the sand's temp. again. It should have had a slight change. Overall, this should help to demonstrate that force equates in to heat or something like that.

Take the grandest magic trick that you have seen and then debunk it using physics. Build your own replica. You should be able to explain the trick by listing ALL possible solutions, then disprove them one at a time. If by chance you've eliminated all the possibilities but one, that one is how the trick was done.

Determine the height and force of which a bowling ball needs to fall, onto a see-saw-type catapult, in order to catapult a basketball through the net from the free-throw line!

you can do a cause and effect project like in the movie Home Alone. What I mean is where you have a complicated set of things do something simple like pour a cup of coffee. We did that in physics class this year.

Here are some ideas:

1. Toothpick/popcicle bridge
2. K'Nex roller coaster
3. Electric circuits (light bulbs/switches, use resistors to control brightness)
