I challenge you all to try to get a 12 to the biggest possible size. Do whatever you can to overinflate it the most. Try inflating and deflating a few times so it stretches or inflate it slowly with a one way valve to get the longest neck. You can even bake it in the oven.
Has to be 12 inch rated size. (Can be any make)
Has to be tied or on a valve.
I will judge entries based on size of the balloon and the length of the neck.
I haven't decided on the prize yet, I'll probably let you design a character or scene for my next story, something like that.
The deadline is next Sunday. (I might extend the time if there's not enough entries.
