Show the Glow.  The FluoroSphere is a fluorescent light show that provides a unique and glowing experience with each use.  Fill the FluoroSphere with water and place it on the UV light stand, add red FluoroGel and watch the show develop.  As the red FluoroGel is dissolved by the water it becomes a highly fluorescent yellow-green.  A beautiful light show that is different each time you fill it.  

How it works

The FluoroSphere is based on fluorescence (the property of absorbing light of short wavelength and emitting light of longer wavelength).  As the FluoroGel dissolves into water it absorbs blue light from the light base and emits a bright yellow-green and/or Red light. 

What's included

4-inch octagon ultraviolet (UV) light base (black light)
6-inch glass orb with silicone stopper and flat bottom
2 x 9ml (RED and GREEN) FluoroGel (Fluorescein concentrate in Mineral Oil)
Not included:
Three (3) AA batteries


Place three (3) AA batteries (not included) into the UV light base. 

If FluoroGel has separated, swirl and shake the bottle to thoroughly mix the FluoroGel solution. 

Remove silicone stopper on glass orb.  Fill glass orb with room temperature tap water.  Leave about a half-inch of space from the opening.  Do not overfill.  Dry outside of glass and place on UV light base.  Turn light base on (press black button on the side)
Make the room dark.  Turn off the lights.  The room does not need to be totally dark and UV base will illuminate some of the room.  
Remove silicone stopper to expose the top hole in the filled glass orb.  
Gently mix Fluorogel again. 
Add 10 to 15 drops of FluoroGel to the orb through the top opening.
Watch the show slowly develop. Take a picture and share it.     
The FluoroSphere can be left on the light base as a room decoration.


Pour out and rinse the FluoroShere in the sink.  Rinse with warm water.  TIP: Turn FluoroSphere upsidedown and at a slight angle to allow the water to flow out of the hole.

    Tripy light show

    We all had a great time with this product from age 12 to 85. We filled the sphere with water and started the show, it lasted about 20 minuets with cool green streaks at first then turns into a cool field of green clouds. It kept our interest the whole time, we played fun music while it was going on.

    This is a very nice product, especially for the money

    I would recommend that buyers pay close attention to the directions as it is very important that the gel is mixed well. I would have added a AC adapter because you could go through a lot of batteries, or use rechargeable batteries like I did. Also, change it up like Pyrofarms suggested to get different results like I did. Perhaps a little larger vial of the gel I would suggest as you could go through this vial pretty fast.
