Water Rocket Guidelines/Info:
- Maximum group size = 3 students.
- The pressure chamber will be made of at least one uncompromised 2-Liter
Bottle*.
- A protected capsule area must be incorporated to hold the foam housing
for a PockeLab Voyager sensor. This capsule area must be a cylinder
with circular ends equal to the rocket fuselage interior cross-section, and
at least 10cm in length.
- The capsule area must have perforations to facilitate pressure
equalization between the inside and outside of the rocket*. A torch
and nail will be provided for this.
- The neck area of the pressure chamber must remain free to accept the
jaws of a Pitsco Aquaport launcher.
- No dangerously pointy objects (e.g. nails) may be attached to the
rocket's tip.
- All provided energy will come from 100psi of added air pressure.
Provided Materials:
- Two 2-liter bottles
- Duct Tape
- Cardboard
- Clear tape
- Hot Glue*
- Lead tire weights.
Crucial Design Considerations:
- High quality fins -- choosing and finding a proper fin material (and a
means of attaching fins) can be challenging.
- Weight added as far forward as possible.
- Symmetry
- Plenty of room for the 10cm long foam insert
