Summary

A fire piston is a primitive method of starting a fire. It consits of a hollow tube plugged at one end and a plunger rod. It uses the principles of heating gas by rapid compression of air in an inclosed space to ignite a piece of tinder. This project uses aluminum and resin to create a modern fire piston.

What You'll Need

·        6in piece of 1/2in Aluminum tubing 

·        7in piece of 3/8in Aluminum Solid Rod

·        Resin – we used West Systems Epoxy

·        Small O-ring

·        Mold making materials

Drill

Hack Saw

Drill press

Standards

  • (HSN.Q.A1): Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
  • (HSA.CED.A4): Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm's law V = IR to highlight resistance R.
