Q: Hello, I am wondering if it would be possible to specify the type of plastic egg used as cargo in the Hang Time event? Like maybe a web-link to the product so we can buy and therefore test the same one as will be used on Olympiad day?
Q: Can the students use dental floss for the parachute ?
A: Yes. We would consider dental floss to be a type of “string” which is listed in section B5 as an Approved Material.
Q: I seem to be having a problem the rocket launcher for Hang time. When I pressurize the bottle with air, it launches by itself and does not wait for me to release the clip. Is there something I am doing wrong or is the launcher faulty?
A: When you are setting up the rocket on the launcher make sure that you have removed the plastic ring from the neck of the bottle so the bottle fits properly on the launcher. Attach the hose and then make sure that all 3 nozzle clips are fully hooked over the neck of the bottle. As you pressurize the rocket you will hear a click as the bottle jumps slightly against the nozzle clips. You will know it is adequately attached to the launcher if after pressurization you can pull on the bottle gently with one hand and it doesn’t come off the launcher.
If you continue to have problems please let us know ASAP. We may need to see a picture or video of your setup to help.
Here is a link to the AquaPort II User Manual. Especially look at Figure 9 on Page 3.
(Please remember when reading the manual that we are NOT using water in any quantity or anything else inside the bottle – just air pressure.)
Here is a video of how to use the older version AquaPort I launcher. Although we are using the AquaPort II the set up is very similar.
Q: Is there a specific guideline as to how the payload should be attached to the rocket? Does the rocket need to have a special payload compartment? Will the students or the judges place the payload on the rocket?
A: It is up to the team how they would like to “attach” their payload. The payload does not have to be physically attached to the rocket body. A payload compartment is permissible but not required. An Event Supervisor, or their delegate, will assist the team in mounting their rocket on the launcher. Once mounted, team members are responsible for making final adjustments to the rocket and payload.
Remember that scoring is based on how long the payload stays aloft. Time will start at the launch command “go” (1, 2, 3, Go) and stopped when any part of the payload or payload assembly (not the rocket) touches the room (wall, floor) or any object in the room (launch assembly, person, etc.).
Q: Minor detail for Hang Time – is duct tape ok? I was thinking of using some Gorilla 1″ tape to hold items a bit more strongly than scotch tape, but didn’t want to get the kids disqualified for it. 🙂
A: Yes. Section B5 of the Event Description simply mentions “tape” as an Approved Material. Any standard kind of tape (scotch tape, packing tape, duct tape, masking tape, electrical tape, double sided tape, etc) is fine. We just don’t want anything that wouldn’t be accessible to the average elementary school-er.
A: One of each payload (3rd, 4th, 5th) was given to your Head Coach at the Coaches Workshop in January.
