Pole-vaulting should be done with a pole-vaulting pole. Do not attempt pole-vaulting with a soda straw, nor with any random stick that you happen to pick up.
The barrier you vault over should not be too tall. Even among professional athletes, few people can clear a wall taller than half a mile. Know your capabilities and choose wisely.
Of course, if you are lighter you can jump higher. There is nothing in the rules against carrying helium balloons when you pole vault. I know, because I checked specifically.
