Description: Prior to the tournament, each team will use 2-liter soda/pop bottles to build one or more rockets propelled by pressurized air and water. Rockets will be launched at the tournament and time aloft recorded. The rocket that stays aloft for the longest time will win.
Event Supervisor: Steve Rossi and Ryan Rossi

Yes, it must be clear. Green Color bottle like 7up or Sprite are not considered clear.
Yes, the rule will be enforced.
Other plastic in the rocket does not need to be clear, meaning only the pressure vessel needs to be clear bottle.
We no longer prohibit the use of any specific glue. Care should be taken to not compromise the integrity of the of pressure vessel when attaching parts to it.
Rocket launches may be called of due to weather.
See the Launch Criteria on our web stie.
Yes,you can use other bottles.
The pressure vessel MUST BE A 2 LITER.
We will provide a step-stool so that students can reach the rocket to make necessary adjustment. WBR station supervisor will also be available to adjust part of the rocket as needed. Once the rocket has been pressurized, students are not allowed to touch the rocket for safety reasons; again the station supervisor will help.
The cancellation of the Water Rocket event on the night before a tournament will stand regardless of how the weather turns out on tournament day.
It is still possible that if the launch is not cancelled the night before, it could still be cancelled if tournament day conditions become unfavorable, as described in our launch policy.
Teams will not be expected to bring their rocket if the launch is cancelled the night before.
In general, no. Each team that has a separate team number must have their own device(s).
For the regional Macomb tournament, every registered team of up to 16 students must have its own device(s). A few of those registered teams are the 2nd team for a school, and are classified as an “Alternate Team”. Two devices from the same school may be very similar in design, but the students who compete are still expected to make their own device. Every device must be marked with the Team number. Accordingly, only one Event Team will be allowed to compete with a given device at that tournament.
At practice tournaments, teams are generally allowed to register more than 16 students, and have “Alternate Team Members” compete. In these situations, there may be more than one Event Team registered for a given event and team number. Those multiple event teams may use the device that has their team number. For more information on participation rules at practice tournaments, see the information published on the Macomb Science Olympiad website, or contact the practice tournament director.
There are no height restrictions this year.
