I've got a bunch of blue (europium based) phosphorescent powder and I'm trying to figure out what to do with it.
I was thinking it might be cool to stick some on the headlight reflector or perhaps integrate it into the inside of the car somewhere...

Any fantastic ideas out there?

 

How about inside your headlamp reflectors? it would make a nice glow at nite and in parking garages

DOH! You already mentioned the reflectors in your post... +1 for ya!

 

Do the headlight reflectors and then your lights will keep it charged. I have some of the Duplicolor stuff but I never did come up with a project for it.

 

I can only think of pranks for this stuff. Is there a nuclear powerplant nearby?

 

I think I might put it in a plexiglass tube and build an oscillation overthruster, or flux converter to go into the area in front of the shift lever.
