Let your cosmic GLOW coaster absorb light energy from the sun, a lamp, or an ultra violet bulb. The higher the light intensity, the more energy the phosphorescent pigment can absorb and the brighter it will glow when it releases the light energy in the dark! Each one comes with a helpful card (see photos).

Available in four colours (this listing is for Silver and purple, see other listings for other colours):
Gold and red
Gold and green
Copper and blue

Diameter: 85mm
Depth: approx. 8mm
Weight: 57 grams

Environmental considerations
Your coaster is sent to you in a recyclable cardboard box made of 59.9% recycled material, using paper tape, not plastic.

Additional information


I’m a fully qualified and experienced science teacher offering a range of hands on STEM education solutions to children aged 4-16 and their educators, through my STEM education business (Sparking STEM). My creative side was feeling neglected however, so a few years ago I found a way to combine my passion for Science education with my love of making lovely things, and developed this ever-growing range of gifts and decorations that aim to engage and inspire whilst offering an element of STEM education at the same time!
