When a balloon is filled to near bursting with SF6 is left in air, it will often burst after a period of time. This is because the smaller N2 molecules diffuses into the balloon while the larger SF6 molecules remains causing the balloon to burst. The simulation on this page allows students to see the pressure difference that causes the balloon to spontaneously burst.
