    Experiment: If you let a very narrow line of water trickle down from the faucet and place a baloon(or plastic ruler, etc) that has been rubbed against your hair very close to the narrow stream of water, the water will curve towards the charged(static electricity?) object. It kinda looks magical and wonderous :wink:


    How would you explain this phenomenon?



    Do you have ideas/links for very simple and safe experiments that can be fun, wonderous or mysterious for kids? :-D

    Read the section on the dipolar nature of water molecules:

    That's pretty neat. I'll have to try that sometime.

    I think the pheomenon is an example of induced charge in a dielectric.
    I'm not sure the polar nature of water molecules is necessary. You would likely get the same effect using a hanging strip of plastic film. It looks so much cooler when you use a stream of water, however.
