At sky -- I live they built a twelve foot in diameter vertical wind tunnel. That's designed for human indoor skydiving. So they don't really college when he publicly beneficial. Lines that already have zero in the pledge here and -- -- -- This season and bears don't -- Day. Now obviously -- titles are great and sending humans up into the air. But there -- also used to test the aerodynamics and all sorts of things. From bicycles to semi tracks to race cars. As aerodynamic and -- Carolina and they're using wind tunnels to research the performance of NASCAR race card they also -- notices you -- transportation like bicycles. And if you want to see the largest wind tunnel in the world check out NASA Ames research. They recently studied the aerodynamics of -- semi trucks to figure out how they can be more fuel efficient. I flag could mean -- -- -- the -- of their time. There were down here and like the -- of the -- today. Underneath where we -- just fine a lot of people are really surprised that there is no -- down here our fans are actually a top four. To -- fifty horsepower fans may actually push the -- how to besides of the building. The air then it's turning beings just like these they turn and -- and ninety degrees and then they get these remains an issue back up. The air is concentrated into one narrow area and many can reach speeds of up to a 180 miles per hour. That it was a ridiculous that would link. The funny thing -- -- that people get totally hooked on ads totally addicting how to do. The amazing you actually really really well really it not just. You can't get it instantly -- of course there. An area where half the.
