“Jam Jar Jet” can refer to two unrelated things: a three-person indie game studio and a jar-based pulsejet project covered in a 2006 issue of Make:. Neither source identifies it as a construction company, building method, or construction product, so the right meaning depends on whether you are looking for games or historical DIY-engine coverage.
What does “Jam Jar Jet” mean?
| Meaning | What it is | Where to look |
