Making Lauging Gas/Whip-its/Nirous Oxide/etc.
WHAT YOU NEED:
o Ammonium Nitrate (NH4NO3) – get a good grade, it’s a fertilizer and comes
in 50lb. bags. Also available from lab supply companies like VW&R or
American Scientific at a much greater cost.
o Clean sand. Fairly fine grained (30 mesh or finer.) If you collect your
and you get fresh water sand, it will be necessary to wash it thoroughly
with water then dry it before using. You must also wash the sand before
o Electric hot plate (500 to 2500 watt) with variable heat.
o Stainless steel dial thermometer. (This is the only metal item which may
be used.) It must go to 250 C (450 F). Select the Erlenmeyer flask (next
item) and the thermometer so that the thermometer can reach at least
within 1/16" of the bottom of the flask through the stopper.
o A 2000 to 4000 ml PYREX or KIMAX Erlenmeyer flask.
o Several feet of 3/8" clear vinyl or surgical rubber tubing.
o At least 4 8mm ID glass or plastic tubing "T’s".
o 1 120 degree bend 8mm ID PYREX glass elbow, with about 3" of tubing on
each side of the bend.
o 7 6-8" long pieces of 8mm ID glass or plastic tubing.
o 3 6-8 feet long 1.5" to 2" diameter glass or clear plastic pipes.
o 1 two hole rubber or neoprene stopper to fit the top of the Erlenmeyer
flask. One hole should fit the 8mm ID PYREX glass elbow, and the other
hole should fit the stainless steel dial thermometer.
o 6 one hole rubber or neoprene stoppers that will fit the ends of the
clear plastic or glass pipes. The holes in the stoppers must fit the
straight 8mm ID glass or plastic tubes.

If you’ve gotten this far – remember – you MUST meet the exact quiality
specifications of the equipment list. If you really want a do-it-yourself
nitrous oxide generator, you want a sturdy set-up you can over and over and
enjoy again and again!
See IFF files included for the diagram of the set-up.
NOTE: When inserting tubing through stopper holes, ALWAYS WRAP AND HOLD THE
TUBING WITH A CLOTH. Also moisten the tip of the tubing and the
stopper hole with glycerin, soap, or spit. (never oil)
1> Into the stopper with two holes, inset the thermometer far enough so
that when the stopper is put into the Erlenmeyer flask, it almost
touches the bottom of the flask (but don’t allow it to touch), and then
insert one end of the glass elbow far enough through the stopper so that
it sticks out 1/4" to 1/2".
2> Into the six one-hole stoppers, insert a piece of the 8mm ID glass (or
plastic) tubing so that 1/2" to 3/4" protrudes from the narrow end of
3> Now select your set-up space so that there is 1.5 feet of space clear in
all directions around the hotplate, so that the three scrubber pipes can
lie side by side where they will not be knocked over.
4> Take approximately 2 feet of the 3/8" flexible tubing and connect
one end to the glass elbow in the two-hole stopper, and the other end to
the middle of one of the 8mm ID glass (or hard plastic) "T’s".
5> With short pieces (select lengths for a neat fit) of 3/8" tubing and
another 8mm "T" assemble the INLET SET manifold and connect it to the
bottom end of the scrubbers. Stoppers may then be inserted into the
lower end of the scrubber pipes.
6> Elevate the OUT end of the scrubber pipes so that the upper end is 6" to
8" above the IN end, but no more, and then fill the pipes with water
until they are full within 4" to 8" of the top (outlet) end, and insert
the outlet stoppers. Try to fill all the scrubbers equally full.
7> With short pieces of 3/8" tubing and two 8mm ID "T’s", prepare and
connect the OUTLET SET manifold to the scrubbers similar to the way the
set was connected in step 5.
8> To the last "T" of the OUTLET SET (of "T’s" manifold), connect a fairly
long piece of 3/8" tubing to reach a "safe" location (where connection
and disconnection of the receiver bags will not disturb the scrubbers)
and secure it. Then put the last piece of 8mm ID hard tubing into the
9> Finally, prepare several receiever bags by inserting about an 8" piece
of tubing into the top so that 3" or 4" sticks out of the bag and secure
it in place with a rubber band.

You are now the proud owner of your very own Nitrous Oxide Generator.
First, prepare a quantity of a mixture containing 1/3 sand and 2/3
ammonium nitrate. Then pour enough of the mixture into the erlenmeyer flask
to give 1.5" to 2" in the bottom of the flask. Put the flask onto the
hotplate, and insert the two-hole stopper, firmly but not too tight. <<This
stopper is your safety valve while the system is operating.>> –BUT–
A Once the heating of the mixture in the erlenmeyer flask has started A
R you MUST REMOVE the two-hole stopper from the flask before turning R

I draw water from the scrubbers back into the hot flask and may crack I
N or EXPLODE the erlenmeyer flask with the steam formed inside. N
Now you may begin heating the flask. Turn the hotplate to medium or
medium-high and watch the thermometer. If the temperature climbs very fast,
turn the hotplate down, but be patient about turning it up. Occasional
bubbles will be noted going through the scrubbers as the air in the system
expands. At 210 C (410 F) a yellowish to orange-brown will begin filling
the flask, and the bubbling throught the scrubbers will become steady.
At this time, adjust the upper end heights of the scrubber tubes so that
each one gets about the same amount of gas passing through it. Keep your
eye on the temperature, and it should not climb much over the 210-220 C
(410-430 F) marks. Also the gas at the top of the scrubbers MUST BE
PERFECTLY COLORLESS! Otherwise, turn down the heat setting. If the gas flow
is too low to give a steady flow throught all three scrubbers, increase the
Once you’ve run your system a time or two, you’ll know what your
operating settings are.
As soon as the gas flow is steady and clean, connect a receiving bag to
the final outlet tube, and allow the bag to fill. It may be necessary to
add more amonium nitrate-sand mixture to the flask from time to time — wear
gloves as the flask will be HOT when removing the stopper. It is also a
good idea to turn off the hotplate while the stopper is out of the flask.
Once you’ve filled a few bags with laughing gas, you’re ready to try some.
Just inhale from the bag and hold it in as long as you can. You’ll know
what to do from there.
