1. A device comprising:
a) a body portion,
wherein the body portion comprises a honeycomb comprised of a porous material,
wherein the honeycomb comprises a plurality of individual cells bounded with one another,
wherein the plurality of individual cells are bounded at a density,
wherein each cell within the plurality comprises a hollow tube, having a wall, a first end, and a second end,
wherein the wall has an inner surface defining an inner dimension of the hollow tube,
wherein the wall has a thickness,
wherein the first and second ends of the tube are open,
wherein the first end of each individual cell within the plurality are aligned,
wherein the second end of each individual cell within the plurality are aligned,
wherein the distance between the first end and the second end of each individual cell within the plurality, and the inner dimension of the hollow tube of each individual cell within the plurality define a volume of each individual
cell within the plurality,
wherein the distance between the first end and the second end of each individual cell within the plurality, the inner surface and inner dimension of the hollow tube of each individual cell within the plurality define a surface area within each individual cell within the plurality,
wherein the sum of each surface area within each individual cell within the plurality defines a total surface area of the plurality of cells,
wherein a first end of the plurality of cells define a bottom surface of the body portion,
wherein a second end of the plurality of cells define a top surface of the body portion,
wherein the body portion has at least one side surface,
wherein the at least one side surface is continuous planar surface; and
b) an active composition,
wherein each individual cell within the plurality is configured to draw in the active composition into the volume,
wherein the porous material of the body portion is configured to absorb the active composition, and
wherein the porous material of the body portion is configured to disperse the active composition via evaporation;
wherein the porous material is a mixture of charcoal and clay;
wherein the device is cuboidal, having a width and length of 43 mm, and a height of 42 mm.
