[PhoeniX VII] "So just wanted to post this and ask if there was anyway you could do semi-accurate gravity experiments on the surface of earth ... "
Yes.
Read about the experiments of Cavendish in almost any physics text. I've also recently seen a page where someone built a Cavendish balance experiment in their basement. From the photos it looked very inexpensive. I'll see if I can find it again and post a link.
Read about the experiments of Majorana in <i>Pushing Gravity</i> (available from this Website, or see if your library can get a copy).
Read about the experiments of Walker and Dual, mentioned in several of the discussions on this forum. (This is the only one that has any potential for measuring the speed of gravitational force propagation.)
Regards,
LB
This is an interest area of mine, so after reviewing some of these things, come back and we can talk shop. I'd like to know what you have in mind.

BTW, be very careful about mentioning FTL anything around your professors. Some will tune you completely out at the first mention. And that can also mean they will block your attempts to use university resources.

Here are two sites that talk about shade-tree experiments. There appear to be others. I googled on "Cavendish gravity". Other search terms might work better.

I don't know if Bill Walker (the Walker in the Walker Dual experiment I mentioned) is still there, but when the experiment was being designed he was at the EE Dept of the Royal Institue of Technology, KTH-Visby, there in Sweden.
That was about 10 years ago.

Pheonix VII,
I wanted to second Larry on his advise of warning (make sure you are the top dog before mentioning FTL, trust me on that one) and read Pushing Gravity. It is a great synopsis of some evidence and speculation from the field. Keep working hard!

Thanks for the responses both of you.
Just wanted to respond with thanks and the information that I did perform the Cavendish experiment. Menaged to get a really nice value on the constant using it and it was really fun performing it.
