How To Pick Up A Beam Of Light With Your Bare Hands
   Light is made of photons, which are easiest to lift if you are made of
   mirrors. However, a beam of light is much more gratifying to lift if it
   is traveling through a liftable substrate, such as a tube of water
   vapor, or a flourescent bulb, and emitted by a light source also within
   the liftable substrate.
   How To Stand On A Cloud
   This is probably best done by placing an air vessel over the cloud such
   that your feet are near the top.
   But it may also be possible to make a very large lightweight mesh that
   would be held up by clinging to billions of water particles.
   Maybe such a huge mesh could also generate electricity from ions in the
   atmosphere and send it to the ground.
   I only have a high school education in physics so I don't really know
   what I'm talking about.
