Bubbles reduce the buoyant force by reducing the density of the water, but if they entrain an upwelling flow of water as they rise, they can produce a large upward drag force on the floating object. In an upwelling flow, our model ship (density=0.94\u2002g\/cm3) floats in a foam whose density is only 0.75\u2002g\/cm3. Comparing results with and without upwelling currents is an interesting demonstration and has real-world applications to ships in the ocean.<\/jats:p>","DOI":"10.1119\/1.3263819","type":"journal-article","created":{"date-parts":[[2010,1,12]],"date-time":"2010-01-12T23:19:01Z","timestamp":1263338341000},"page":"139-141","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Can bubbles sink ships?"],"prefix":"10.1119","volume":"78","author":[{"given":"Michael A.","family":"Hueschen","sequence":"first","affiliation":[{"name":"Palo Alto High School , Palo Alto, California 94301"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3","published-online":{"date-parts":[[2010,1,12]]},"reference":[{"key":"2023071506000991100_c1","volume-title":"Physics for Scientists and Engineers","year":"1996"},{"key":"2023071506000991100_c2","doi-asserted-by":"publisher","first-page":"1064","DOI":"10.1119\/1.1383600","article-title":"When do bubbles cause a floating body to sink?","volume":"69","year":"2001","journal-title":"Am.
