The Slime should slowly flow through the bottle and come out of the open threaded end of the bottle over a period of many minutes. You can adjust the viscosity of the Slime by adding more or less than the specified 60 mL of water as you make the Slime. Slime is a non-Newtonian fluid.
The Slime should appear dull green in daylight or in the presence of ultraviolet light from a UV lamp. It should appear deep red-orange when viewed by the light of an incandescent lamp from behind. Fluorescein fluoresces at 470 nm, in the near ultraviolet.
Warning: The ingredients used to make this Slime are believed to be non-toxic, but as with any chemicals, extreme care must be used in handling and manipulating them.
