This is a video of a tractor trailer full of aerosol cans exploding on the M1 motorway between junctions 20 and 21 in Leicestershire, England. It's believed the cans were ignited as a result of the heat generated by friction after the driver slammed on his brakes following a blown tire. Obviously, I only wish I could have been there-- "So you smell it." You really get me, you know that? I expect the best Christmas present from you this year.
Keep going for the vertical video.
Thanks to Christopher C, who agrees that is not how you pop popcorn.
