1 - Limerick

If you wanted to go to the moon
you wouldn’t go in a balloon.
    The hot air inside
    gives a nice quiet ride,
but you'd come back to earth much too soon.

2 - Senryu

With all that puffing
    his cheeks, so round, so scarlet
         – just like the balloon.

3 - Diamond poem

             Blow,
           puff hard.
        That’s better,
      getting  bigger,
balloon’s fat and round.
     No more blowing,
       that’s enough.
          Look out.
            Bang!
