I want to do a physics experiment, that is rudimentary, yet fun and not very difficult.One not is not refined for perfection :)

A very very simple one:

Fill a bowl with some liquid that doesn't catch fire, place a couple of burning matches in the middle and put a glass over it :p watch the liquid be sucked into the glass (which is upside down) due to the vacuum created by the matches :pp

I've always been a fan of generating current due to changes in magnetic flux. Obtain a coiled wire (1000 coils or so) and a relatively strong bar magnet. Complete a circuit and attach an ammeter to the circuit. Move the bar magnet through the coils and you will see that current has been generated.

Not so fun :(

Hah cool, maybe instead of an ammeter, I could add something else. I don't think we have a ammmeter. I'll think of something :) Thanks.

Sounds cooler on paper.

It doesn't do anything except move a needle.

Try getting a long copper (Or any nonmagnetic metal) tube and dropping a strong ring magnet down the center. It's awesome.

Maybe I could set it up so as one magnet falls down, it makes another one jump up :)

Actually it falls in slow motion.

big magnet vs small magnet? Slow motion would be pretty cool too.

It has to fit inside the copper tube so it has space to move, but still be a close fit.
