How an Air Stream Can Support a Cupcake
Jones, Evan
Physics Teacher, v53 n5 p264-265 May 2015
Variations of a demonstration in which a sheet of paper or a bead is levitated in a grazing stream as from one's breath have been published in several sources. Even a massive ball can be deflected into the robust flow from a leaf blower. The attraction is surprising because it is often quite stable and seems to conflict with the familiar transient repulsion felt from a stream's impact.
