National FAQ: Could the container contain another substance before the water is added? (section: 4 / paragraph: b / sub-paragraph: iv / line: 1)
A: Yes, the container may contain another substance before the water is added.
National FAQ: If the expanded gas in 4.b.xi. inflated the balloon in 4.b.i., does that count as two scorable actions? (section: 4 / paragraph: b / sub-paragraph: i, xi / line: 1)
A: No, an action may count for only 1 Scorable Action at a time.
National FAQ: Does rule 3.i. imply that any electrical device which runs for more than ten seconds would be a construction violation? (section: 3 / paragraph: i / sub-paragraph: / line: 2)
A: Any type of electrical or spring action that operates for more than 10 seconds and still controls part of the action would be a violation. If a light bulb, fan, etc. remained on but was no longer used or no longer affected the device in any way to contribute to points it could be allowed to stay on without penalty.
National Rules Clarification: (section: 4 / paragraph: b / sub-paragraph: xi / line: 1)
A: 4.b.xi. should read: "Use a change in temperature which expands a gas to activate the next action."
National Rules Clarification: (section: 4 / paragraph: f / sub-paragraph: / line: 1)
A: 4.f. should read: "Timing and scoring begins when a competitor pulls a magnet from the device and stops when the beginning of the word 'END' is heard or when 180.0 seconds elapses, whichever comes first."
National Rules Clarification: (section: 4 / paragraph: b / sub-paragraph: vi / line: 1)
A: 4.b.vi. should read: "Use light to initiate the next action."
National FAQ: May the "next task" started by the timer be the Final Action (4c)? (section: 4 / paragraph: g / sub-paragraph: iii / line: 1)
A: Yes, the timer may start the Final Action.
National FAQ: Will teams be allowed to use microcontrollers, Arduinos, integrated circuits, etc.? (section: 3 / paragraph: f / sub-paragraph: / line: 1)
A: Yes, but they can only activate one action and must comply with all the rules including taking no more than 10 seconds to activate an action. They may not be used to control multiple actions. They are considered an adjustable object therefore are only allowed in one transfer per microcontroller, Arduino, integrated circuit, etc.
National FAQ: What differentiates a chemical from a mechanical task (in reference to a timing mechanism)? (section: 4 / paragraph: g / sub-paragraph: i / line: 1)
A: For timing purposes, If a chemical reaction causes a mechanical action, once the mechanical action initiates the next action, no more chemical timing points can be earned even if the reaction continues.
National FAQ: May we use sealed lead acid batteries? (section: 3 / paragraph: j / sub-paragraph: / line: 1)
A: No. Sealed lead acid batteries are not allowed. They could be considered considered hazardous material per Rule 2.d.
National FAQ: May a single battery source whose total output does not exceed 14.4 volts as labeled be used for more than one action and receive the bonus points for 1 battery source? (section: 5 / paragraph: e / sub-paragraph: / line: 1)
A: Yes, because a single battery source is not “moveable/adjustable” it may be used for more than one action as long as it complies with all other rules and if it is the only battery source in the device the team will receive 100 points.
