The helium gas is one of the most simple sources of fun, no kid or adult can resist to that temptation of trying at least once to play a little bit. It is used mostly to give you a high-pitched voice, even for the ones that have a deep one, making you talk funny at least for a few seconds after sucking the gas. When everybody is tired of speaking like a cartoon character, it can still be used to fill balloons. Since the helium gas is lighter than air, it will instantly move up if you don't hold it down. That's the main idea for this version of Bloons, you will have several balloons inside jars that will fly up high as soon as you break the glass with your dart kit. Your goal is to blow them up before they get out of sight, are you up to such a challenge?
