The host of the show, Ross Shafer, suggested he do some scientific demonstrations in a six-minute segment, and take on the nickname "The Science Guy".[14] His other main recurring role on Almost Live! was as Speedwalker, a speedwalking Seattle superhero. From 1991 to 1993, he appeared in the live-action educational segments of Back to the Future: The Animated Series in the nonspeaking role of assistant to Dr. Emmett Brown (played by Christopher Lloyd), in which he would demonstrate science while Lloyd explained. The segments' national popularity led to Nye hosting an educational television program, Bill Nye the Science Guy, from 1993 to 1998. Each of the 100 episodes aimed to teach a specific topic in science to a preteen audience, yet it garnered a wide adult audience as well.[15] With its comedic overtones, the show became popular as a teaching aid in schools. When portraying "The Science Guy", Nye wears a light blue lab coat and bow tie. bill nye the science guy,bill nye the science guy full episode,bill nye the science guy season 1,bill nye the science guy dinosaurs,full part

https://www.armasight.com/ In this video we give you guys an in depth overview of the Armasight Zeus Thermal Optic lineup. These optics are simply amazing, and with that commands a premium over other standard optical devices. A quick note guys, some of the footage may appear to be lacking in contrast but when you are out in the 100° F Georgia heat filming this video it doesn't help matters. With a cooler background, such as in a nighttime scenario, the contrast between subject and background would be far greater and easier to distinguish. We hope you enjoy this fun look at Thermal technology, and be on the lookout for more footage filmed using these optics in other videos as well as overviews of other thermal units and night vision devices in the future.

REVIEW - Unertl, US Optics, Vortex Razor HD - SNIPER 101

Order: Reorder
Duration: 21:56
Updated: 25 Dec 2012

The USMC issued Unertl MST-100 scope, the US Optics ST-10 and SN-3, and the new Vortex Razor HD scopes are compared in this review. Rex examines their long range suitability for the LONG RANGE 101 series. 1. Unertl MST-100 is a great scope for the .308 Win and was designed for the USMC M40 sniper rifle. Rex reviews the interesting features on this optic and categorizes its long range suitability. 2. US Optics ST-10 is the most rugged scope you can get and has some of the best glass in the world. If you want an extremely tough battle optic that will put up with whatever you throw at it... this may be it. Price is way too low even at $1600 considering it beats most scopes that cost $1000 more. The SN-3 is the toughest variable scope you can get and has top notch glass as well. If you really want a variable power scope and want ruggedness at the same time, look at this scope. 3. Vortex Razor HD has some great feature design and looks like it should be a great choice, however, conflicting reports as to construction quality loom in the air. Rex cannot endorse or reject the Vortex Razor HD at this time...
