How does a gecko walk up a glass wall? It's not glue, it's a kind of static electricity!
Nature's Example:
The bottom of a gecko's foot is covered in millions of tiny, tiny hairs. These hairs get so close to the wall that they create a tiny electrical attraction (like static cling) between the foot and the wall. This is enough to hold the gecko's whole body weight.
💡 Fun Facts
- Scientists are copying this idea (called 'biomimicry') to make super-strong 'gecko tape' that can stick things to a wall without glue.
- A gecko can 'unstick' its foot by simply peeling its toes, which breaks the tiny electric bonds one by one.
