00:00:07in a previous video I made a fire piston
00:00:10out of some scrap acrylic and a
00:00:12lawnmower handle this little tool can be
00:00:13used to start a fire by squishing air
00:00:15and since it’s completely see-through
00:00:17you can witness the ignition firsthand
00:00:19whether you use it as a tool for making
00:00:21a survival fire or to explore the
00:00:23science of heating through adiabatic
00:00:24compression it’s always gratifying to
00:00:26get a spark and make a plan I called it
00:00:28a slam rod firestarter which apparently
00:00:30has been added into Wikipedia that kind
00:00:33of blows my mind I’ve had a lot of
00:00:34requests from people who would like to
00:00:35have one but don’t really know where
00:00:37they can find any acrylic to make it so
