SCIENCE OLYMPIAD Egg-O-Naut - C CeAnn Chalker

Egg-O-Naut Teams will design, construct, and launch rockets carrying an Egg-O- Naut to stay aloft the greatest amount of time without breaking the Egg-O-Naut

General Info 2 rockets are prebuilt by team members Rockets must be made out of a 1- liter or smaller plastic carbonated beverage bottle Inside diameter of nozzle of approximately 2.2 cm Only ONE 1 liter or smaller plastic carbonated bottle will be used as the pressure vessel for each rocket

Construction Label must be presented if removed Structural integrity of pressure vessel may not be altered. Ex: Physical damage Thermal damage Chemical damage Safety check will be done

Construction Cont’d Adhesives are limited to glue that may be used to attach components to the pressure vessel Silicone Polyurethane based Others that do not damage the structural integrity of the pressure vessel

Construction Cont’d No commercial model rocket parts Rockets launched using launcher provided by the supervisor Fins must be 2 cm above the level of the flange on the bottle’s neck Only water/air pressure will be used for energy to the rockets

Construction – Egg portion Grade A large raw egg Egg must be easily removed Egg may not be altered Egg will be marked by Event Supervisor Egg portion of rocket may separate from the pressure vessel

Competition Walk in event Wear safety glasses Students will add water, load egg, launch, and retrieve their rockets 5 minutes to launch 1 or 2 rockets (only 1 launch per rocket) Rockets launched before time expires will be scored

Competition Cont’d Rocket will be launched at 60 psi Once rocket is pressurized, no one may touch or approach the rocket Timing ends when the Egg-O-Naut or portion of the rocket containing the egg touches the ground or comes to rest on anything

Competition Cont’d Teams must retrieve their rockets and immediately show the capsule with the egg to the event inspector Capsule or wrapping must be opened in the presence of an event official.

Scoring Greatest time aloft Plus – bonus seconds for Egg-O- Naut capsule separation Plus – bonus for Egg-O-Naut survival Team’s score will be the highest score of either rocket

Scoring Bonuses Egg-O-Naut or portion of rocket that contains the egg detaches from the pressure vessel = 3 seconds bonus Surviving egg = 15 second bonus Nonretrievable egg = 7.5 second bonus

Violations Safety violations (including no goggles) will not launch and receive only participation points 3 second deduction for construction violations not related to safety

Tie Breakers 1 st Tie breaker Longer time aloft of the shorter flight 2 nd Tie breaker Longest length of rocket on the launcher of the longer flight
