A few years ago, Charlene gave me a "Glow in the dark ceiling Nightscapes™" kit from Toysmith Group2
The box contains an instruction manual, 4 different sizes of 6" or so long acrylic rods and one wire one, for different magnitude stars, a small specimen cup, a bottle of glow in the dark paint, and the projector assembly (which is part of the box). This is a little "grain of wheat" bulb inside a plastic dome, a battery holder, and a layer of box that has a positive template of the northern summer night sky. Turn on the bulb, set the template section slightly askew on the bottom, it projects a very dim display on to the ceiling.
On January 3, 2014, we finally got around to painting the ceiling.
If we were to do it again (and we may do another room):
- Many online reviews mention that the bulb is fragile. Our original bulb glowed briefly and then burned out, we tried various LED options ('cause we had them lying around), they all projected little pictures of the LED shape on the ceiling. You really need a point light sources, we ended up replacing that bulb with a "grain of wheat lamp" bulb, either from Fundemonium (our local hobby store) or Radio Shack, I forget which.
- We clipped the rods in half so each of us would have a full set. This was plenty long, and stayed upright in the specimen cups well. A bit of tape on the clipped end gave us an in-the-dark cue of which end to use.
- The flattened box top makes a good shadow so you can see what you have and haven't painted.
Tonight we see how it actually looks.
