Hydrogen Rocket
O-Ring Set (2 ea)
CAUTION
This product uses citric acid crystals to assist
in the generation of hydrogen fuel. Citric acid
is found in everyday food products. Short –
term exposure to citric acid can irritate eyes,
skin and your respiratory tract so handle with
care. Exposure would be like getting lemon
juice in a cut or in your eye. If your skin or
eyes come in contact with the crystals, flush
with plenty of water for several minutes. If
you ingest the crystals, rinse your mouth with
plenty of water.
HOW IT WORKS
By passing an electric current from six D batteries in the Launch Base through a solution of tap water and
citric acid crystals in the Fuel Generator, the water solution breaks into hydrogen and oxygen gases that
bubble upward in the generator. This process is called electrolysis. The hydrogen and oxygen gases collect
in the upper chamber of the Fuel Generator until there is enough to launch. When the Launch Button is
pressed, a special igniter in the generator heats up to ignite the hydrogen gas collected in the upper chamber.
The expanding gases from the ignition of the hydrogen thrusts the rocket into orbit. After ignition, the hydrogen
combines with the oxygen again and turns back into water!

BATTERY SAFETY
To prevent the possibility of severe injury to you and others or damage to your HF launcher and rocket:
1. Never place or allow anyone else to place any part of his/her body over the launch tube.
2. Never launch when anyone is within 15 feet (5m) of the launcher.
3. Never launch your rocket so that people or animals are in its flight path.
4. Always launch outside in a large open space like a sports field or playground away from power lines, trees, buildings and busy
roads.
5. Launch only when there is little or no wind and good visibility.
6. Never launch any item or rocket except rockets designed specifically for the HF launch system. An HF rocket must have special
recovery system designed to return the rocket safely so that it may be used again.
7. Never attempt to catch a descending rocket. Keep everyone clear of the rocket’s descent path.
8. Never attempt to retrieve a rocket from a power line or other dangerous place
9. Never attempt to alter the HF launcher or HF rocket in any way.
10. Never use any material or liquid in the HF launcher other than water and the crystals in the ratio provided.
11. In case of misfire stop pressing the launch button, release tension on the launch cable and wait 60 seconds before allowing anyone
to approach the launcher. Flip the power switch to “OFF”, while examining your rocket and launcher. Never place or allow anyone
to place any part of his/her body over the launch tube.
HYDROGEN ROCKET SAFETY CODE
No fuel being generated (can’t see any bubbles):
• Power Switch not ‘ON’.
• Batteries low and need replacement.
• No solution in Fuel Generator.
• Generator not reset after launch.
• Generator sat idle for 6 minutes or longer and shut down.
Rocket will not launch:
• Power Switch not ‘ON’.
• Fuel Generation time not long enough.
• Solution not allowed to soak into generator long enough.
• Launch Cable not held taut enough to activate Safety Switch.
• Launch Button not held down long enough.
• Igniter in Fuel Generator wet with solution.
• Rocket not all the way down on Launch Tube.
• Small O- Ring on top of Launch Tube missing or not seated properly.
• Rocket Body and/or Fuel Generator cracked or broken.
• Rocket not launched before "Launch Tone" stops.
If you see damage to any area of the fuel generating system, launch assembly or rocket, do NOT attempt to generate
hydrogen fuel or launch rocket. Call the Estes® Customer Service Center at 1-800-525-7561 ext. 216 for assistance
or replacement parts.
TROUBLESHOOTING
You may wish to keep your launch system assembled with the solution remaining in the Fuel Generator for future
launches. If so, be sure that the Power Switch is “off” and the rocket is removed from the Launch Tube. If you do not
plan on launching for a couple of days, we recommend that you disassemble and store your Hydrogen Fuel Rocket
System as follows:
5. Carefully pour the solution back into the plastic
storage bottle and then cap the bottle. Remember
the solution may have a brown color but it is still
good to use. Do Not Discard Solution.
6. Rinse Fuel Generation Assembly out with tap water.
Let air dry.
7. For extended storage, remove the batteries from
the Launch Base.
1. Turn the Power Switch “OFF”.
2. Slide the Rocket off the Launch Tube.
3. Twist, unlock and remove the Launch Tube.
4. Twist, unlock and remove the Fuel Generator,
being careful not to spill the solution.
