- 2016-01-18 10:26 Do the plastic bottles have to be exactly 500-600 mL or can there be slight variations in size such as pint (~450 mL) or a quart (~800 mL) plastic containers that are readily available to students in supermarkets.
Normal plastic drink bottles ( water or soda) are between 500 and 600 ml. This is why that range was chosen. It will be up to the event supervisor to determine how close to that range they will accept. Teams should be prepared to stay within that range.
- 2016-01-18 10:26 May the cups or spoons be measuring cups and measuring spoons?
- 2016-01-27 21:12 Must the 500-600 mL plastic container with lid have a manufacturer's mark indicating the volume or can the students use a container that they have determined to be in the 500-600 mL range by their own measurements?
The requirement is that the container be 500-600 ml. There is no requirement that the container have a manufacturer label to that effect.
- 2015-11-12 13:27 May students bring pipettes to measure the drops of lemon juice/vinegar? The rules do not specifically require event supervisors to provide them and if the student's prior research was measured using drops, they will need them.
No, the students can not bring pipettes. The event supervisor may provide them, but the students should not plan on that.
- 2016-01-16 19:51 Rule 2.b. states that Supervisors will provide “… other reagents or equipment to complete the experimental activities.” My Question: Does this include timers so that the when conducting the lab tasks, each team can time their experiment in...
Yes, students may bring a timer.
- 2016-01-16 19:54 Do we have to know the chemical structure of all types of sugars, starches, etc. or just ones that pertain to dairy?
All test questions should be related to dairy food science.
- 2016-02-09 20:02 This rule says the difference between the ES's mass and the student's mass is to be scored. Rule 4 b. ii does not score the difference when student mass > ES mass. Which rule applies in that case?
10 points is the maximum number of points. The masses will be confirmed by the event supervisor and points awarded based on their measurements. If the students mass > ES mass, the team will score 10 points.
- 2015-11-12 13:29 Can students bring something to "fasten" the cheesecloth over the beaker such as a rubber band or will that be provided by the event supervisor?
Students may only bring what is listed in the rules. All other materials should be provided by the event supervisor.
- 2016-01-16 20:09 When the curds have been drained for 15 minutes, are they to be squeezed and dried before determining the mass of the curds?
Yes, they should be dry. Please see the training guide posted on the National Website under Food Science.
- 2015-11-12 13:57 The rule says using heavy cream. We only found heavy whipping cream in supermarkets. Can we use heavy whipping cream for our experiments?
Yes, Heavy Cream and Heavy whipping cream are similar differing with the percentage of fat. Heavy cream is about 36% and heavy whipping cream is about 30% milk fat. The students should practice with different types of cream because you don't know what type of cream the event supervisor will provide for this Lab.
- 2016-01-16 20:12 50 minutes does not seem long enough to complete two tasks and the written test. How much time is allotted for the written test?
The written test may be given during the entire time period so the students may work on it during the experiment portion. This is up to the event supervisor.

- 2015-11-12 14:33 Is the CD that the blades are mounted to only held on to the generator by the detent balls on a CD player or can extra support be provided such as double sided adhesive tape to strengthen the joint?
Yes, as long as the tape is easily removable and does not impact other subsequent teams' testing.
- 2015-11-12 14:35 Rules state that "Power generator general questions...."Does this refer to the general question of how electrical power is generated in each of these types of power plants or specifically to the generator itself?
Anything related to power generators in general is a valid question, which could include aspects of the power plants.

- 2016-02-11 10:40 Regarding the use of electronics. Can an electric drill be brought to detach the weight and subsequently (after impound/before event) reattach the weight before launch? If so, does it need to be impounded?
Yes a drill may be used as a tool and it does NOT need to be impounded. Please keep in mind that power outlets might not be available close to the competition area.
- 2016-01-29 19:17 Can we re-inflate the air chamber after launch (ie: soda bottle, when it's crushed) using ambient air, to go back to it's original shape, or does it need to re-inflate itself?
Yes,you may re-inflate the air chamber provided the chamber is at ambient pressure at launch.
- 2016-02-09 19:08 3d states an 80cm cube may be used at "any orientation." This is not possible due to the furtherrestrictions in 4a.
Correct, if teams choose to use the max 80cm size, they are then limited in the orientations they may place the device in. Smaller devices will have more possible orientations available.
- 2015-12-14 09:24 Can the calibration of the device be electronic, if it is not a physical part of the device? (Meaning, it can be added, calibrated, and then removed before the firing of the device).
Yes, tools are allowed to be electronic. Electronic devices may only used during calibration.
- 2015-11-12 13:04 Team must provide unmodified light weight plastic or foam golf balls to be used as projectiles. Are practice plastic golf ball with holes on the side consider "Unmodified"?
Yes, plastic golf balls purchased with holes in them are considered unmodified and are allowed.
- 2016-01-15 20:16 May competitors be in front of the launch area BEFORE a launch? Specifically: Are competitors allowed to walk behind targets to instruct their partner in aiming their device?
General rule #1 applies (https://www.soinc.org/ethics_rules). There is no prohibition in the rules about approaching or going behind the targets prior to a launch during their 8 min. time period (rule 4.f.) During a launch they must follow rule 4.b. Teams may be penalized if they disturb the competition area.
- 2016-01-14 21:09 Can competitors use a laser as a material to help with setup, adjustment, and calibration of the device? General rules about laser use will be followed and the laser impounded.
Yes, lasers may be used as a tool for setup, adjustment, & calibration of the device. They must be removed prior to launch. The laser policy posted on the National website must be followed.
- 2016-01-15 20:19 Is a rope which extends from the device to the target considered a calibration tool?
A rope can be considered a calibration tool as long as it is removed from the device during each launch.
- 2016-02-09 19:24 If a team qualifies for 2 bucket shots, must the bucket shot be constant for both shots or could the event supervisor select different locations for each bucket shot?
There is only 1 location for the bucket which is the same for all teams and all launches.
- 2016-01-15 20:26 The rule says a distance of at least 2.00 m must separate the targets. If the near target is on the 2 m centerline would it be legal for the far target to be 2m to the right or left perpendicular to the centerline 2 m mark?
Yes, that is allowable.
