hmmm I know that there is a small type of graphite that works well, any other resource?

Awww...well what are some easy levitating resources? I know that there's a special type of graphite that works well...any other?

So I want to levitate...(drum roll please)...A REALLY SMALL WORM! First off, I read that the downward pull on the worm will be gr (gravity times density), so then how would I calculate how powerful my magnet would have to be to balance this force? So that's the mathematical part...

How much power would it take to levitate a worm? A small one...

I heard that graphite works as well (I think it was graphite), would a small piece of wood work well?

Going back to the diamagnetic talking... Can someone tell me how much force a magnet would need to have to lift a frog or something with about that much mass?

Thank you for the answer it helped a lot. I wasnt sure whether it was telling me to use the first or second way, but now i know its the trigonometric way (i think i spelled that right)

Okay so I am reading a book on analytic geometry because my algebra class is starting to really bore me, and I ran across this: slope = m = -1/2 (easy enouph) but then it states "since the slope is the tangent of the angle of inclination θ, we have: tan θ = -1/2 okay so I guess my...

Thank you :D

I understand how it works...but I am trying to think of some variables to use becuase we have to use the scientific process :/ So far all I have thought of is using different mediums between the laser and the slits, or maybe perform the experiement at different speeds

nevermind i figured it out

First off, I didnt know where to put this so I just stuck in where I though it seemed to go best (i didnt really want to put it in the homework section). Here's my problem: My teacher is making us (my 8th grade class) do individual science fair projects and compete them at the regional...

Thanks for the advice, I appreciate it

@ micromass what about the professors?

@ eri: What do you mean by "you need a lot more" do you mean you need a lot more than the math I am planning to take, or you need a lot more as in things that make you stand out
