The Meteorite

Description: I wanted the meteorite to look radioactive with a pulsating glow. Good luck finding a pulsating black light (though you could create a fading circuit with a blacklight LED. Those LEDs cast a lot of purple light, though). I came up with this approach that works pretty good.

First, I needed a meteorite. So, I got a balloon and some Great Stuff spray insulating foam. I wrapped the balloon in plastic wrap just in case the spray foam ate through the balloon and caused it to pop (I don't know if you have worked with this stuff before but it is very sticky and impossible to get off your skin. I wasn't going to risk a disastrous sticky bomb). I taped the balloon into a plastic bowl and spayed the top of the balloon. Let dry.


Then, I popped the balloon, removed the plastic wrap the best I could (don't worry about getting all of it), then put a layer of foam on the inside of the foam bowl I had created. I wanted a good cavity but put too much foam so it filled up more than I would have liked. No big deal. Immediately after applying the foam, I sprinkled and hurled some decomposed granite (available at any nursery) onto the wet foam. This added some much needed texture.


Once it was all dry, I attacked it with a power drill to add a few more crevices. I then spray painted it with a stone color, followed by some black spray paint to make it look scorched. I then used a fine brush and some green glow-in-the-dark paint available at art supply stores and painted some green in some of the cracks. I then followed it all by a very light dusting of green fluorescent spray paint (available at Home Depot). the final result looks pretty good.
