The high mobility of Leidenfrost drops is commonly attributed to the lack of contact with the hot substrate, and it makes them sensitive to tiny forces, such as gravity or airflows. We show that droplets generate their own dynamics and self-propel despite the absence of external field, which contributes to their legendary mobility.
