Move side-to-side rather than forward-backward to maximize the difficulty for the person aiming at you.

You could hide behind a rock, a tree, or a bush.

If your opponent is throwing balloons designed for water fights, known as water bombs, they will have a harder exterior and will be much easier to catch. If you’re fighting with cheaper party balloons, you may want to avoid trying to catch them because they will break more easily. If you fail to catch it, hitting an incoming balloon with your hand can either deflect it away or pop it away from your body so your clothes won’t get as wet.

Keep in mind that the water will shift around in the balloon. If you’re having difficulty handling the balloon, it may help to hold your hand underneath the balloon and throw it overhand in a catapult motion.

Too many fake throws could cause the opponents to get annoyed and target you. Use your fakes judiciously.
