Ok, i know there is Telekinesis, Pyrokinesis, and Hydrokinesis....

Is there any other "kinesis" things? if so, what are they? and what do they do?
For example, Pyrokinesis is fire, Hydrokinesis is water...

could it be that all the features in the face and body could be indication of wither or not your healthy. And could it be that beauty is not so vain after all.

That their is purpose of seeking a partner that will serve you well in health. that beauty is an instinct in us to tell wither or not that he or she will be with you for all time.

I know of the existence of these devices in the early 1900's.
They were used to determine whether a particular pebble was likely to be useful as a crystal radio component.
But do they still exist, and what are they called?
Is there a schematic or even a description?

How would one be built, if they are no longer sold?

All help is appreciated, thanks.

1. The effect of different liquids on teeth
2. The effects of salt and other contaminants on rate of rusting
3. The effect of temperature on the growth rate of crystals


For #1, I was thinking about using either real teeth or egg skins to represent the teeth. Then I'd use three liquids (probably milk, orange juice, and soda) and see which dissolves the tooth or egg the most in a given amount of time.

For #2, I was thinking about using three different contaminants to see which would make an iron nail rust fastest. Any ideas for the contaminants?

For #3, I'd grow crystals somehow (?) and see if growing them in the cold differs from growing them in warmth.

Which one do you think is best? How could I go about doing these experiments? Any suggestions for different experiments?
