What I've tried to do is listen the most to people who have had the most success. In the cases where two people say different things, I've tried to list it so you can try both and see what works for you. The world record set by Susan Montgomery Williams was done with more than 3 pieces of gum. I believe that Bubble Yum, the company holding the blow-offs, were afraid of kids choking themselves on large wads of gum or parents complaining about their children always getting their product in their hair and clothes. The 3 piece rule was put into effect, and nobody bothered to make sure the record conformed to it.
New wisdom is always welcome.
Pick a better brand of gum Popular brands of bubble gum go through great lengths to make sure the consumer enjoys their product. Below is an incomplete and unscientific ranking of some types of bubble gum that I have used. I'd like to point out that these ratings are based on diameter, meaning someone who can blow a 4 inch bubble with Bubble Yum will probably blow a 10 inch with Freshen-up. It is manufactured in New Jersey, but I have had some luck finding it in the larger 7-Eleven stores here in Colorado. You can't just yank a popped bubble off your face like you can with Bubble Yum.
