Thompson calculated that if one piece of weight could lift 45 pounds, more pieces could effectively handle his body weight. Not exactly complicated math but math nonetheless! He then attached the famous Flex tape to some shoes and gloves. And that's it!
That was his entire plan. The question now becomes did it work? Well, that all depends on your definition of "working. It should also be noted that the wall in question must be unpainted because the paint would stick to the gloves and shoes making them useless. It all sounds a bit crazy to us but it's fun to watch! The study shows why geckos are the largest animals able to scale smooth vertical walls. In climbing animals, from mites and spiders up to tree frogs and geckos, the percentage of body surface covered by adhesive footpads increases with body size, setting a limit to the size of animal that can use this strategy because larger animals would require impossibly big feet.
David Labonte and his colleagues found that mites use times less of their total body area for adhesive pads than geckos. Once an animal is big enough to need a substantial fraction of its body surface to be covered in sticky footpads, the necessary morphological changes would make the evolution of this trait impractical, said Labonte.
