Here in Australia we do get the up on the other end of the spectrum quite often during summer however although that doesn&#8217;t really drive us to do much more than sit around a pool and drink copious amounts of beer. So you can imagine then that anything involving sub-zero\u00a0temperatures\u00a0is going to be somewhat intriguing to us, especially something as cool as this:<\/p>\n<iframe title=\"Bubble freeze\" width=\"668\" height=\"376\" src=\"https:\/\/www.youtube.com\/embed\/53iE0fKcu5o?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<p>There&#8217;s nothing particularly complicated about what&#8217;s going on here but the demonstration is quite novel. What you&#8217;re seeing is the formation of ice crystals on the surface of a soap bubble which starts off slow but ramps up significantly as more crystals form. I think this is partially due to the way crystals form as they usually need a rough surface to attach to. This is how those <a href=\"http:\/\/www.youtube.com\/watch?v=lISK1YFcZBM\" target=\"_blank\">instant ice videos<\/a> work as the bottles don&#8217;t have any anchor points for the crystals to form but once you shake it up a bit you give them a surface to attach to.<\/p>\n<p>There was one question that was left unanswered due to the video cutting off at the end however: whether or not it&#8217;d still float after it was frozen.<\/p>\n<p>Now the bubble isn&#8217;t increasing in mass, it&#8217;s simply changing forms. There&#8217;s the possibility that some of the moisture from the air outside the bubble will condense onto the crystalline surface however I don&#8217;t think that&#8217;d change the mass by an appreciable amount. The density would also be going down as well thanks to water&#8217;s intriguing property of getting less dense as changes into ice. All those factors together would indicate that a frozen soap bubble would behave in much the same way as a regular one but I&#8217;d still like to see this hypothesis tested.<\/p>\n<p>Although I do much prefer warmer climates, so this will have to be an exercise that&#8217;s left up to the reader.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Thanks to our northern hemisphere counter-parts I&#8217;ve been privy to all sorts of interesting cold weather things from making instant snow\u00a0to the\u00a0ingenuity\u00a0that people come up&#8230;<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[13],"tags":[2378,4222,1413,4221,2895,4223,1144],"class_list":["post-4802","post","type-post","status-publish","format-standard","hentry","category-science","tag-bubble","tag-crystals","tag-formation","tag-freezing","tag-ice","tag-soap","tag-water"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/ppBqt-1fs","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/posts\/4802","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/comments?post=4802"}],"version-history":[{"count":0,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/posts\/4802\/revisions"}],"wp:attachment":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/media?parent=4802"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/categories?post=4802"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/tags?post=4802"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
