I understand that cyanocrylates (super glues) have come a long way. I understand that they are used in cars and airplanes today and can create an incredibly strong bond.
That said, I have a hard time believing that a few drops of commercial off the shelf super glue can be used to hold several TONS of weight.
Loctite created this commercial advertising their superglue doing just that. Supposedly with just 8 drops of glue, they were able to hold over 2.5 tons of weight.
Gorilla did a very similar advertisement.
Is this really possible or is there some trick at work here?
