An amazing video shows a behind the scenes look at the creation of a glass car - no kidding! It's almost completely made of glass. Shell Oil wanted to really show everyone how their engine oil works by making a see-through car, including, of course, the engine itself. The engine turns over, and you can clearly see the Shell Helix Ultra lubricant splashing about making the transparent car's engine parts all move smoothly.
Before you get too excited and want to print off a glass car of your own on your 3D printer, you must realize that the team who pulled this off had to hand craft more than two thousand parts and very carefully fit them together for this to work. So, no, you can't print out a glass car yet. Well, perhaps the ashtray.
