A suspension of corn starch and water is an example of a non-Newtonian fluid that you can experiment with as you&#8217;ll see in this week&#8217;s video. I used an amplified speaker covered in some plastic wrap to hold the mixture know as &#8220;Oobleck&#8221; which derives it&#8217;s name from the children&#8217;s story &#8220;<a href=\"http:\/\/en.wikipedia.org\/wiki\/Bartholomew_and_the_Oobleck\" target=\"_blank\">Bartholomew and the Oobleck<\/a>&#8221; by Dr. Seuss. The sine wave is generated by my laptop running a free program called <a href=\"http:\/\/www.trueaudio.com\/rta_down.htm\" target=\"_blank\">True RTA<\/a>. It&#8217;s a real time frequency analyzer available for download. When the sine wave is played through the speaker, strange things happen to the Oobleck and it rises up to dance around! <\/p>\n<p>Have fun with this one and&#8230; keep on hackin!<\/p>\n<p><iframe loading=\"lazy\" width=\"640\" height=\"360\" src=\"http:\/\/www.youtube.com\/embed\/WOrdOgSIh0U?list=UU3v9cVoEt4YqZpGyzewdlrQ\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Non-Newtonian fluids are strange.
