El Hormiguero – Spanish TV show

El Hormiguero (Spanish for “The Anthill”) is a Spanish television program focusing on comedy, science, and guest interviews. Pablo Motto hosts and produces the show which is being broadcast on Antena 3. In one segment of the show scientific experiments are presented. This episode shows a tie which repels red wine and textiles which repel sand. Further experiments demonstrate that drops of a liquid can be encapsulated by hydrophobic sand to form so-called liquid marbles. Under the demonstrated conditions these liquid marbles can be moved over water like boats. The experiments on the liquid marbles were performed in cooperation between the Max Planck Institute for Polymer Research (Germany) and the Osaka Institute of Technology (Japan).
