Antique Bulldozers and Crawlers [HD]
A large collection of vintage and antique crawlers. Many were unrestored and look like they should not even run, while others have been restored and look like they just rolled out of the factory. Bulldozers have a scraping blade on the front, while others are simply called "crawlers" or tracted-tractors. Filmed at the Tulare Antique Farm Equipment Show, Tulare, CA
MERCURY vs SALT - Defies ALL LOGIC
What the what? Jeff uploaded something besides a GUN video? Why am I speaking in third-person? How is this even possible? We pour mercury on top of table salt. Hg is 7 TIMES denser than salt- the salt should float. Why doesn't it just freely float to the surface? This is not CGI or camera trickery. It's not stunt-salt or magician's mercury... Mercury is a toxic, heavy metal. We use all precautions needed to do these experiments. Often I just make it look like I am being sloppy just to mess with people who aren't paying close attention.

RUMELY Oil Pull Primitive Tractors (w/ slomo)
Interesting old Rumley Oil Pull tractors. These ran on all types of kerosene instead of other types of fuels like gasoline or diesel. The engines had a huge displacement and some had pistons 10" in diameter and a 12" stroke. I tried to find some details about these, and found limited specifications about them. They used oil instead of water for cooling because the engines needed to run much hotter than gasoline engines to ignite the kerosene. The engines are often started on gasoline, then switched to kerosene once it warmed up. Water was also injected into the engine to prevent predetonation under heavy loads and it was common to burn 1 part kerosene and 1 part water in these conditions. These were used a lot for threshing operations in the U.S. and Canada, and many were in operation during WW2 to help feed the nation. I got a few shots in slow motion at 300 frames per second.
