StratoFins Screw-on Water Rocket Fins for Soda Bottle 2 Liter or Smaller
StratoFins Screw-on Water Rocket Fins for Soda Bottle 2 Liter or Smaller
Description:
StratoFins® 
screw-on water rocket fins are compatible with 95% of all 
available launchers either homemade or commercially available in 
the marketplace including those employing a rubber stopper (4M), 
an expanding tube (AntiGravity), nozzle (Quest), O-ring (Aquapod), 
or cable ties (H2O Thruster) because it replicates the threaded 
portion of the bottle beyond the fins. (
2 
liter soda bottle, launcher, nose cone & parachute NOT included
)
StratoFins® 
will guide your rocket to lofty heights with straight flights 
instead of tumbling through the air without fins.
StratoFins® 
are made of durable plastic and screw-on to a 2 liter soda 
bottle or smaller.
The 
StratoFins® kit includes 1 attachment ring and 3 fins along with 
an instruction sheet that provides information for creating a 
nose cone and several launching tips.
Assemble 
StratoFins® by sliding each fin down a separate slot on the 
attachment ring beginning from the top. With all fins in place 
screw the attachment ring onto a soda bottle until snug.
This water 
rocket can be launched with or without a parachute attached 
since this configuration does not nose dive, but instead tumbles 
gently back to the ground provided the nose cone is not 
permanently attached.
Great item 
for people of all ages for fun, science projects, school 
classes, parties, etc.
StratoFins® 
requires no tools or glue for assembly.

Fins and parachute make all the difference in the world in performance and fun when using a water rocket launcher. You will 
be amazed how high only 40 PSI will propel a bottle with fins 
attached to it, which is only 1/3 the pressure that you could employ.
