Lorsqu\u2019elles s\u2019accumulent dans le m\u00eame environnement, les bulles forment de la mousse, et plusieurs types de mousse nous sont utiles au quotidien. Certains aliments et certaines boissons se d\u00e9gustent avec de la mousse, comme le caf\u00e9 ou les smoothies. Divers produits d'entretien et m\u00e9dicaments utilisent \u00e9galement de la mousse.<\/p>\n<\/div>\n<p>N\u00e9anmoins, cr\u00e9er les bulles parfaites pour chaque type de mousse est relativement difficile ! Sur Terre, le m\u00e9lange de gaz et de liquide qui forme la mousse peut tr\u00e8s vite changer. La gravit\u00e9 attire le liquide entre les bulles vers le bas, tandis que les petites bulles r\u00e9tr\u00e9cissent et que, le plus souvent, les plus grosses grandissent. Rapidement, la mousse s'effondre et devient liquide. C'est pourquoi les bulles d'un bain finissent elles aussi par \u00e9clater, m\u00eame quand on ne les touche pas du doigt !<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"4288\" data-credit=\"NASA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2009\/10\/De_Winne_with_the_Foam_Stability_experiment\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2009\/10\/de_winne_with_the_foam_stability_experiment\/9979121-2-eng-GB\/De_Winne_with_the_Foam_Stability_experiment.jpg\" alt=\"De Winne with the Foam Stability experiment\"><figcaption>De Winne et l'exp\u00e9rience sur la stabilit\u00e9 de la mousse<\/figcaption><\/figure>\n<p>Imaginez si nous pouvions \u00e9tudier la mousse sans que la gravit\u00e9 ne d\u00e9truise les bulles. Eh bien figurez-vous que c'est exactement ce que font les chercheurs \u00e0 bord de la Station spatiale internationale ! Les conditions d'impesanteur de la Station permettent aux bulles et \u00e0 la mousse de subsister plus longtemps. En 2009, l'astronaute de l'ESA Frank De Winne a men\u00e9 \u00e0 bord de l'ISS une exp\u00e9rience sur la stabilit\u00e9 de la mousse. Il a d\u00e9couvert qu'il \u00e9tait possible de cr\u00e9er des mousses extr\u00eamement stables dans un environnement spatial sans pesanteur !<\/p>\n<figure class=\"wp-block-embed is-type-video\"><iframe src=\"https:\/\/www.esa.int\/content\/view\/embedjw\/533124\" width=\"640\" height=\"360\" frameborder=\"0\"><\/iframe><\/figure>\n<p>Les recherches sur la mousse ont permis d'am\u00e9liorer diff\u00e9rentes formes de production de nourriture. Selon C\u00e9cile Gehin-Delval, sp\u00e9cialiste senior en recherche et en d\u00e9veloppement pour les laboratoires Nestl\u00e9, en Suisse : \u00ab La stabilit\u00e9 des bulles de mousse peut am\u00e9liorer la qualit\u00e9, la texture, le go\u00fbt et la conservation de certains aliments et certaines boissons. Cette \u00e9tude nous a aid\u00e9s \u00e0 cr\u00e9er des bulles d'air presque parfaites pour nos produits laitiers, nos cr\u00e8mes glac\u00e9es et nos aliments pour animaux domestiques. \u00bb<\/p>\n<p>La prochaine fois que vous prendrez un bain, observez la mousse et pensez aux astronautes qui jouent avec des bulles dans l'espace !<\/p>\n<p><i>Fait int\u00e9ressant : on peut m\u00eame fabriquer de la mousse \u00e0 partir de m\u00e9tal. La mousse d'aluminium est aussi r\u00e9sistante que le m\u00e9tal pur, mais bien plus l\u00e9g\u00e8re !<\/i><\/p>","protected":false},"excerpt":{"rendered":"<p>Do you like to play with bubbles in your bath?
