Applied Science | Two laps at 24 Hours of Lemons (Sears Pointless 2013) @AppliedScience | Uploaded 11 years ago | Updated 5 hours ago
Two of my cleaner laps at Sears Point. My team, Back to the Crapper (#82) placed fifth in our class, and 30th overall out of 180 cars. This is only my third race, and I have a lot to learn about driving.

But it does work well.) Holography Marketplace book lots of very practical information for making your own holograms, and good source of suppliers (though many are out-of-business now): https://www.amazon.com/Holography-MarketPlace-6th-Franz-Ross/dp/0894960997 Very good source for mold making supplies: https://shop.smooth-on.com/ Countermeasures against hologram copying. Holograms are often used as a security seal, so making copies as shown in the video could be a problem without countermeasures: http://www.nli-ltd.com/publications/countermeasures.php I was planning to talk more about different types of holograms in technical detail, but I think I will save it for a future, dedicated video on making original holograms. https://www.patreon.com/AppliedScience$
