Are there any parks you can use?

The overall weight of rockets would be lighter, due to the usage of 1 liter bottles rather than 2, but the air compressed would also be less than a 2 liter, when both are pumped to a constant PSI.
And finally, a question: would ES(s) enforce the rule of only using carbonated beverage bottles as pressure chambers? For example, I've seen 1 liter SmartWater bottles being used before, but those aren't carbonated, are they? I say this because it really limits the shapes available to competitors, whether we're using a carbonated bottle or not, and it could put those who thought exclusively of carbonated bottles at a disadvantage, if non-carbonated bottles are loosely allowed. What are your thoughts on pressure chamber shapes/bottle brands?

Does the egg need to be placed into an easily accessible compartment or can it be placed in a location that will then be sealed up by tape during the launch?
What can you bring with you to prepare the rocket with the egg and prior to launch? Are there any restrictions? Is the egg only placed in the rocket during the 10 minute window prior to launch or can it be loaded prior to that?
