N\u00e4r det finns m\u00e5nga bubblor tillsammans kallas det skum, och m\u00e5nga typer av skum \u00e4r anv\u00e4ndbara i v\u00e5r vardag. Vissa livsmedel och drycker blir b\u00e4ttre med skum, till exempel skummet p\u00e5 kaffet eller i en milkshake. M\u00e5nga reng\u00f6ringsmedel och l\u00e4kemedel anv\u00e4nder ocks\u00e5 skum.<\/p>\n<\/div>\n<p>Det \u00e4r dock sv\u00e5rt att skapa de perfekta bubblorna f\u00f6r olika typer av skum! P\u00e5 jorden b\u00f6rjar blandningen av gas och v\u00e4tska som utg\u00f6r ett skum snabbt att f\u00f6r\u00e4ndras. Tyngdkraften drar v\u00e4tskan mellan bubblorna ned\u00e5t, och de sm\u00e5 bubblorna krymper medan de st\u00f6rre ofta v\u00e4xer. Det dr\u00f6jer inte l\u00e4nge f\u00f6rr\u00e4n skummet bryts ned och blir till v\u00e4tska. Det \u00e4r d\u00e4rf\u00f6r bubblorna i ditt bad till slut spricker, \u00e4ven om du inte petar p\u00e5 dem med fingret!<\/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 med experimentet om skumstabilitet<\/figcaption><\/figure>\n<p>T\u00e4nk om man kunde studera skum utan att tyngdkraften f\u00f6rst\u00f6r bubblorna?

De tyngdl\u00f6sa f\u00f6rh\u00e5llandena ombord efterliknar avsaknaden av tyngdkraft, vilket g\u00f6r att bubblorna inte spricker lika snabbt och skummet f\u00f6rblir v\u00e5tt l\u00e4ngre. \u00c5r 2009 genomf\u00f6rde ESA-astronauten Frank De Winne experimentet \u201dFoam Stability\u201d p\u00e5 den internationella rymdstationen.
