Each protrusion, in turn, has hundreds of microscopic filaments. The intermolecular forces (called van der Waals forces) that emanate from these filaments are sufficient to hold the lizard’s weight ​ — even when it is scurrying upside down along a glass surface!
Igal harjasel on omakorda sadu mikroskoopilisi harusid, mille tippude tekitatud molekulidevahelistest jõududest (van der Waalsi jõud) piisab sisaliku keharaskuse paigalhoidmiseks, isegi kui see loomake jookseb pea alaspidi mööda klaasist pinda.
