See rule 4.b.i
The task seems to be similar to last year except with some more stringent requirements.

Re: Balloon Task
Does anyone know what "unguided" means? Does that mean the balloon can't touch any walls?

Re: Balloon Task
That's a great question. It would definitely mean the device can't be designed so that the balloon expands through a constrained tunnel of sorts.ET2020 wrote:Does anyone know what "unguided" means? Does that mean the balloon can't touch any walls?

Re: Balloon Task
I expect this is going to be a controversial and difficult question, with multiple FAQs over the course of the season. In talking with several people with input into these rules, there is disagreement even among them as to the definition of unguided.Unome wrote:That's a great question.

Re: Balloon Task
If I have the balloon expand downwards, would gravity be considered as a "guide"? If not, then does placing a mass into the balloon count as having a guide?

As I said above, "unguided" is horribly vague - there will need to be an FAQ.Brov wrote:If I have the balloon expand downwards, would gravity be considered as a "guide"? If not, then does placing a mass into the balloon count as having a guide?

Re: Balloon Task
Oh, yeah definitely. I've heard there was even debate over whether gravity counts as guidance. I'm rather concerned about the precedent this would set, since 1. gravity is a fundamental phenomenon that will affect the balloon no matter what and 2. If gravity is considered guidance, what laws of physics are safe, and which ones aren't?

Re: Balloon Task
Guided means that you are forcing the balloon to expand in a way different then it would if it was expanding in the open.

Re: Balloon Task
What forces count? Gravity, electrostatic, bouyant? Is hanging the balloon upside down gravitational guidance?Jacobi wrote:Guided means that you are forcing the balloon to expand in a way different then it would if it was expanding in the open.
