I just learned this week. With regular gum, not bubble gum -which my daughter assures me is more difficult. Nothing basketball sized, but a few golfballs. I gave up shortly after trying as a teen, and assumed I'd never be able to.
Can you get bubblegum in flavors other than "bubblegum"? I only like peppermint flavor these days. I used to like Juicy-Fruit.
Also I prefer the "tablet" style with a crunchy shell. Those brwnish sticks are so much less appetising and don't have the same "bite"
My kids assure me apple/pineapple layers is THE best, but I'm not ready to take out another mortgage yet.....
