(I'm already in alubarna part of arabasta arc ^-^)Yes,sensei!
~Grabs one of your ballons,I concentrate chakra on my palm and begin to rotate the chakra in clockwise direction,then i make it flow into the water of the ballon,making the water inside rotate clockwise but every seconds that pass,the water rotates faster and faster and faster,finally managing to burst the ballon~
KA-BOOM,sensei!
*The balloon bursts in mere seconds.
Great, you'll get better with time though.
SECOND STEP!!! POWER!!!
*gives ya a pack full of rubber balls*
Do the same as you did with the water ballon, concentrate on rotation but now make it rotate more powerfully. This should result in a KA-BOOOOOOM, in less than one second.
Summarizing simply do the same as the water ballon, but make the spinning force much stronger.
