Physics Girl's video: Make sand a liquid

Bubbling air through sand can cause it to act like a liquid. Dianna Cowern and William Osman try to reproduce this popular GIF on Physics Girl. Sand liquefied! Support Dianna during her recovery at patreon.com/physicsgirl The glass beads used in place of beach sand were called "Multipurpose abrasive blasting media, Glass Beads." We bought 60-120 and 70-140 Mesh Size and ended up using the larger diameter beads. http://physicsgirl.org/ http://twitter.com/thephysicsgirl http://facebook.com/thephysicsgirl http://instagram.com/thephysicsgirl Creator: Dianna Cowern Editing: Jabril Ashe Animations: Kyle Norby Thanks to William, John, and Kyle Kitzmiller
