Water Rocket Fin Ideas!
A great feature of the StratoLauncher IV is it enables students and family members to create their own fin and rocket designs by merely screwing on the nozzle and it will launch. Rather then limiting fin design to duct tape and cardboard, encourage your participants to be creative by supplying them with an assortment of materials, adhesives, and tools.

Fin Building Tips:

  1. Chose lightweight stiff materials (balsawood, coroplast, carbon fiber sheet, or gift cards).
  2. Employ a fin jig for evenly spaced and correctly aligned fins.
  3. Position fins as much at the tail of the rocket as possible.
  4. Sand surfaces where adhesive will be applied for greater grip.
  5. If using Loctite PL Premium Polyurethane Adhesive, then allow at least 48 hrs. for curing before use.

Also, don’t forget to retire and discard those old bottes/rockets from last year that are stressed and deformed from multiple pressurizations. These old stressed bottles may explode even at pressures below 120 PSI. It is always a good idea to start the season off with fresh new bottles.
