what surfactant do you recommend, im struggling to find any information on
it.
kind regards

Nikolai,
I viewed your tutorial video, there are many things about it that I like.
It is well made, you clearly put a lot of effort and thought into it, and
you provide instructions in an orderly well-explained manner (sadly, a rare
quality when it comes to You tube videos). And I can tell you have a lot of
experience under your belt with PVC rocket motor making. You present a lot
of good ideas (your dessicator is better than mine, I'll have to get one of
those rubber sealed containers).
There are certain things that make me cringe, regarding safety, you
probably know what I am referring to. So on one hand, your tutorial is a
good for entry-level rocketry, but I hesitate to recommend it to anyone
without a fair degree of experience with sugar motors, who would have the
needed awareness of hazards.
As such, I do have one suggestion to make the process better and safer.
I would ditch the sugar (sucrose) based propellant for a safer, and far
less messy one, such as sorbitol or dextrose (KNSB or KNDX) and use the
conventional casting method. Safer and neater. If casting poses a problem
with small diameter casings, a surfactant (commonly available) will
eliminate that issue by making the propellant pour like water. I expect
that since you've been working on this for 5 years, you probably have
gotten comfortable with the materials, and that propellant choice, but
maybe its time to consider my suggestion. I'll bet you will like it and can
make an even better and safer version 2.0 of your otherwise very good
tutorial.
cheers
