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
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.
1/3 Scale Working Steam Tractor
I have almost no information on this extremely well-crafted homebuilt steam tractor. The machinist who made it spent over 3500 hours fabricating it. I am estimating it is 1/3 scale. Equiptment show in Tulare, California. I was tired and dehydrated after 6 hours of filming and lugging around 3 cameras. Here is a link to the owner's channel where you can see this tractor driving around, and even hooked, via belt drive, to an ice cream maker! Steamed Cream! http://www.youtube.com/user/ADSankey
MERCURY-Filled Water Balloon - Science!
Mercury, also known as quicksilver, is a very dense liquid metal. It remains a liquid down to about -40c. Normally you would have to fill a water balloon using a hose or a pump. But because mercury has a density that is about 13.5 times that of water, you can just fill a water balloon by just pouring it in using a funnel. Be sure to watch my other Hg videos where we do simple demonstrations that show the remarkable properties of this unusual element. http://www.youtube.com/playlist?list=PL786EBDC8D2B4CD1D - - - -My Mercury Videos: http://www.youtube.com/results?search_query=taofledermaus+mercury&aq=f - Music by Zero-Project "e-world" http://www.jamendo.com/en/album/85671 - Interesting Mercury Facts: http://www.prospectorsparadise.com/html/mercury.html
