Well you need to be prepared. There are many ways to do this and you could find a load of prep stuff along with a few techniques. I have been a successful Cryokinetic myself, I can create mist and freeze water. Holding ice cubes in your hands works. You also have to take cold showers. Once you've properly done a few techniques you can make up your own. One I made up was where I create frost all over a given point in the yard. Anyway, if you want help with Electrokinesis too, I can provide a lot with that. I get up every morning and turn on lights without touching anything, and I walk downstairs and the TV turns on and the channel changes to sports center. Hope this helps.
Addition to that answer:
All that sounds like a lot of discomfort and hard work. A far faster technique is to get yourself a bit part in the right comic strip and work your way up till you can freeze out the lead character. If it is a really upmarket comic strip you might be able to get them to write in a lot of other super-powers as well.
Like a good knowledge of science, logic, mathematics, technology, and human relationships. Addition again: Actually although holding ice cubes in your hand seems to condition your body, it damages your skin. And taking cold baths seems like an extreme. It's not necessary to condition your body that way.
The ability to control the element of ice.
If you mix hydrokinesis (ability to manipulate water) and gelidkinesis (ability to manipulate ice), you may create cryokinesis, the ability to control cold temperatures and create ice. This hybrid kinesis would allow you to manipulate both water and ice elements with mastery over freezing temperatures.
Credits to http://en.wikipedia.org/wiki/Psionics Since matter and energy are related, these energy based abilities may be actually considered "mind over atomic/subatomic matter" control wherein something like Pyrokinesis and Cryokinesis are simply the control of motion of molecules within an object. Therefore, in this context the term psychokinesis would suffice for all of these varieties. * Psychoportive abilities ("travelling through space/time or metaphysical plains") ** Teleportation ** Astral Projection ** Etherealization ** Dimensional Travel ** Time Travel
Well, there are many. There's telekinesis, pyrokinesis, hydrokinesis/cryokinesis, electrokinesis, geokinesis, aerokinesis, photokinesis, umbrakinesis, etc. The ones I listed (other than telekinesis) are the 7 elemental psychic powers. There are many more. By mastering the use of spirit energy, one can not only use these powers, but also do things such as teleport, fly, and even absorb blows via the manipulation of your aura. I am a psychic myself, and let me tell you. If you want to learn any of this, you need to practice regularly. I hardly have much time to practice myself due to college.
Some mystical powers include telekinesis (moving objects with the mind), precognition (seeing the future), teleportation (instantaneous travel), and shape-shifting (changing physical form). These abilities are often depicted in folklore, mythology, and fantasy stories.
