These are cool but I do it for older people and not as a contest but as a skill I learned because I didn't listen to my teacher when she told me not to chew gum. Take it from there. Do it slow and not all at once. Stretch a little chew a little etc. I wouldn't have kids stretching chewed gum all over the place. I don't think they'd ask you back. If you're on the comedy side you'll want a few packs hanging around.
