Glow In The Dark Pebbles
These will make an interesting addition to any patio or garden, glow in the dark pebbles. By day they look like ordinary stones but at night they glow like radioactive elements.
The pebbles charge up during the day and will glow for up to 6 hours at night, so when you roll in from the pub you’ll be able to see the pathway to stagger down rather than demolishing the nearby flower bed.
You can get 350 glow in the dark pebbles from Collections Etc. for $9.99 [found via eco friend]
