    Follow instructions precisely

  • I couldn't get this to work at first. I thought I followed the instructions exactly. After a bit of tinkering I did get it to work. I had to use just a tiny bit (more like a little fluff) of cotton (from a cotton ball of 100% cotton). Then, I had to push very hard, as if I were trying to push the plunger through the bottom. I recommend using a very sturdy surface. After making sure I did both of the above, it worked every time I tried.

  • I tried everything and could not get it to work. After reading the reviews and looking it up online on a demonstration video.... We found that the plunge must be quick and hard and done on a hard stable surface. Now it works every time. My son had so much fun with it, he wanted to do it over and over and showed to his friends. There is also an interesting history on it.
    Very Impressive...not for the weak

  • Works very well. Probably 100 shots with the single cotton ball that comes with the kit. Easy for an adult male to make work but even a strong 10yo boy doesn't have the strength to get it to fire. Great tool...just know the limitations.

      Fire Syringe Demonstrator

      This "fire syringe" or diesel piston demonstrator device shows the relationship between gas pressure and temperature – and how they can be used to start a miniature fire! The piston apparatus consists of a thick, clear plastic tube and a plunger. When the plunger is pushed down, the air in the tube is compressed, elevating the temperature enough to ignite a cotton ball. Includes instructions on how to use the fire syringe demonstrator.
