A recycled Mushroom Cloud LAMP
There are enough good ideas presented here to make me think fires can be safely avoided. And I want the thing to look 'active' somehow. Yesterday I suggested putting a heat driven, full-o-holes can around the lamp to make the light intensities change but someone pointed out that such would require HEAT, the thing we're trying to avoid. Bad idea; good observation. It dawned on me that many xmas tree lights blink and that "the lamp" could be made from such (?). Actually that idea arrived well before dawn...Another pre-dawn idea was to connect the lamp to a morning wakeup device (clock radio). Hack the circuit which fires the buzzer so it turns on the lamp. Could be named the "F. N. BadMorning" alarm. F and N could be Full Nuclear but I think I'll pronounce it "Effen". I'm gonna have to build one. Maybe Goodwill has the alarm I'll need. - c2builder

You killed a teddy bear for this? Say it ain't so! Somewhere there's a flaccid bear stretched out like a dead jellyfish;( Anyway, I did a similar thing back in '90 using urethane foam w/some blacklight paint that made it glow @ the top. Good job! No more bruins though, I can';t bear it! - GregQ
For safety, you could have a perspex or glass tube round the LED. That would allow for venting from below through to the top and would avoid direct contact with the cloud fibre. - AdrianF15
just my ideas...FWIW1. Plan on testing your lamp in a place where a fire won't hurt more than the lamp. I use my outdoor grill for such experiments - and I have had one project ignite there. It was no problem - except for the piece itself - and the cleanup.2. I would only use an LED bulb on this lamp (not incandescent) and I would work to keep the cloud material several inches from the bulb. The cloud material might need holes near the top to let hot air vent.3. I would test the lamp with a higher wattage bulb than was going to be used in the house. Maybe the indoor lamp would have an LED which gave off the equivalent of 40 watts - so I'd test in the grill with 60. BTW, you could also _measure_ how hot the cloud material gets...4. If the lamp ever falls over, changing the size or shape of the cloud, it would be wise to retest the lamp again.5. Maybe _steel_ wool could be used in place of cotton. ?could it be pulled apart to make the cloud material? It would need paint. U.S. hardware stores typically carry steel wool. - c2builder
LED bulbs cost about $8 to $15 depending on the wattage equilivent - BenL46
hmm, good point ! I hadn't thought of that...Regarding the LED power values: yes, I know that a ?4-6W LED? bulb puts out the same light as a 40W ? incandescent but with 1/10th (?) the heat (not sure what those #'s should be). With a small enough true wattage value and, perhaps, some venting near the top, there shouldn't be a fire danger. I may have to try this out. I think the overall idea is wonderfully creative and I'm happy to spend more than $5 to make it safe.Here's a challenge for you inventor types: figure out how to modify this wonderful lamp idea to use any rising air within the lamp to turn a cylinder (metal can?) full of randomly drilled holes. The bulb should be inside the cylinder and the light escapes to the cotton thru the holes. The effect would be that the mushroom cloud would appear to roil angrily (I hope). The can would also focus the hot air up the center of the lamp. You'd probably need to hide some vent holes in the top of the can and in the cloud above the can. - c2builder
