Repeat Michelson-Morley's "Ether Wind" experiement
Then, compare it to W. Kantor's repeat of the experiment, showing different results.

Here's a cool one.
It is known that projectiles travel in a parabolic path. Or, to be more exact, the center of mass of a projectile travels in a parabolic path. Even if the projectile breaks up into multiple pieces during its trajectory, the center of mass of those pieces will still travel in a parabolic path, as long as no external force is exerted on the pieces.
Create an exploding projectile launcher and use it to verify this proposition. Or, if you don't believe me, test it as a hypothesis.
Use two dice as your projectile(s). Use some sort of rail as the support for your launcher. Angle it upwards. Attach a big spring to the base of your rail, and attach a small cup to the free end of the spring.
In one trial, tape your two dice together. Put them inside the cup, and launch them. Measure the distance they traveled. In another trial, launch your two dice without taping them together. The average distance the two dice traveled should equal the distance the two traveled while taped together.
You can do variations on this project, such as adding clay to one die to make it heavier, thus skewing the center of mass. You can also create a more elaborate launching/separating mechanism.
Be sure to take into account the mass of the tape, etc.

How about angular motion. (I think that's what it's called) Demonstrate, which will reach the end of an incline first. A spool of duct tape, A can of chicken noodle soup, or a can of frozen juice. The results are interesting.

Two words: Coil Gun.
you get electromagnetic force from the coil driving the projectile, and you get projectile motion from the, well, projectile.

Thermonuclear device would be cool.
