"Stuff" as in "stuff it, it's useless". Last time I used it was the last time, not fun, the first couple of shots worked, then it was all hairspray and no boom. I never did get to applying engine start (ether?) but it's definitely flammable!

Then your seals aren't up to quality (any leaks equals loss of compression), your design is off, (improper fuel load in relation to combustion chamber size, improper projectile resistance/weight/mass In relation to firing force, or your assistant chickened out and didn't properly tighten the rear plug), or you simply didn't use enough hairspray."Stuff" as in "stuff it, it's useless".

Yeah sorry, I fixed it. It's a slingshot - a 'wrist rocket.' Very powerful and effective against plastic and foam. It would obliterate that machine . Silent, legal and about 10 bucks.Image not showing
okNot sure if that'll actually be enough to damage the sensor on the go pro.
However, people should really (really) avoid those cheap laser pointers. They are often listed as being 1 mW or 5 mW, but in reality they can produce much more power. Green (532 nm) pointers always look really bright because they are near the wavelength of peak sensitivity in our eyes so it's hard to know how powerful it really is.
The cheap pointers also tend to leak a lot of NIR light. There is generally a fairly powerful 808 nm laser diode, which pumps a gain material to generate 1064 nm light, which is then frequency doubled to 532 nm. With cheap lasers there is little to no filtering to remove residual 808 nm and 1064 nm light which - while we can't see it - can still damage our eyes.
I confiscated one from a student during a practical class, then took the student to my lab so we could check the pointer using a power meter, it registered about 80 mW (even though it was advertised as <1 mW).
Whatever happened to the invading drone?
That's why I suggested a pellet gun.
