Split the players in to 2 equal teams,

the player at the front holds a blown up balloon under their chin, no hands allowed,

they then have to pass the balloon to the next in their team so it's under their chin, and so on down the line to the end, keeping the balloon under their chins as they pass it along.

The first to the end is the winner,

or last player to the front and repeat until the first player is at the start again.
