This kit has been my most popular item!
And because of this, I have increased the number of fluorescent
minerals to 15 and have added some other fun things to do with
fluorescence-like ink, paint, and an invisible ink pen. Kit
includes:
 |
Long wave lamp |
 |
Batteries
|
 |
Explanation,
instructions, and fun activities
|
 |
15 long wave
fluorescent rocks |
The Long Wave lamp is not harmful and can be
taken outside at night to discover the fluorescent rocks in the
family driveway. As these stones
are loose, please protect young children.
