In geometry, a strophoid is a curve generated from a given curve C and points A (the fixed point) and O (the pole) as follows: Let L be a variable line passing through O and intersecting C at K. Now let P1 and P2 be the two points on L whose distance from K is the same as the distance from A to K (i.e. KP1 = KP2 = AK). The locus of such points P1 and P2 is then the strophoid of C with respect to the pole O and fixed point A. Note that AP1 and AP2 are at right angles in this construction. In the special case where C is a line, A lies on C, and O is not on C, then the curve is called an oblique strophoid. If, in addition, OA is perpendicular to C then the curve is called a right strophoid, or simply strophoid by some authors. The right strophoid is also called the logocyclic curve or foliate.

Liquid oxygen accelerates styrofoam cup combustion
I poured a little liquid oxygen into a Styrofoam cup, then ignited it. The Styrofoam burns very quickly in the oxygen environment. At the end of the video, I stomped on the burning mess, and the confined combustion between my shoe and the ground creates a loud pop.
