I think you need this popper thing. First you're just gonna get two balloons, then you're just gonna grab one of your balloons and blow it up and tie it off. Next you're just gonna take this balloon and put it inside of this one. Once you've done that just cut off the top. Be careful not to cut the balloon on the inside. Once you've done that you're finished. And the good thing with this is if it pops on the plane, there would be like no water spilling, no beads everywhere. And there probably wouldn't even be a noise because when I had air balloons pop, it just kind of starts to go flat. So yeah, hope this helped. Bye guys!
