That’s casted aluminum and is the actual frame of the vehicle I believe. Check out the jerryrigeverything video where he breaks the frame on one of these, I think it’s the same stuff. Super thin cheap foamy casted aluminum so cheap it looks like plastic.

Makes sense, it beats paying licensing for every screened device.

No he’s right. The solution for an optimal surface area to volume ratio is a sphere. The farther you deviate from a sphere the less optimal you become. The actual math for this is finding deltaSurfaceArea in respects to cylinder radius for a given volume and then finding the maxima, which is a Uni physics 1 problem I really don’t feel like doing. Long story short, optimal is when height = diameter, or as close to a sphere as a cylinder can be.
