Boom! The classic potato gun harnesses the combustion of flammable vapor. Show us your combustion spud gun and discuss fuels, ratios, safety, ignition systems, tools, and more.
Thanks for the advise i will try to corporate a syringe on it, but if the power doesn't satisfies me i will inject some oxygen
i used a syringe this time and it still doesn't work!!! i also vented very well the chamber too. I'm really angry and curious, why doesn't it work? The same problem i have with all my combustions (only 2)
