Paint Your Car With Rustoleum
Giant Fresnel Lens Deathray: An Experiment in Optics
Professional grade duct tape bike leg strap
I bought a lens on a stand at a rummage sale, they said it was used to magnify a small screen. That sounded fun. It was big so I left it on the porch. Next day I noticed someone must have tried to set our porch cushions on fire! A day or two later there were more burns in the porch cushions. Eventually I figured it out....when i think of what could have happened because i didnt realize what was happening. That said, it is very cool, but not for the uninformed.
DirtCheapDaily on YouTube did this too. He spray painted his car in his driveway. Gotta love this blue, it looks totally wicked. https://youtu.be/dZr560JW5Ck
i dont understand do you put it on top of the paint? or as the primer? also how many coats is good?
@SelenaH5 Please read this page again and again and again until you understand it.1. The lens focuses a large area of sunlight to a fine point. Whatever is at that point gets very hot, even just air, it starts to glow brightly and start to burn - even metals and glass will melt, concrete burns. This includes you, your hand, your brain if you're that uncautious. This is dangerous stuff.2. The glow can get as bright as the sun, after all it comes from the sun, and that will damage the eyes of anyone looking at it. You do not want to blind anyone, a school is fir the education of the ignorant, and it's likely someone who's ignorant will ignore or not understand any warnings you put up, Never underestimate the capacity of the human being to be stupid, Health and Safety is designed to plan for these as among the vulnerable.3. The project may cause other people to try to emulate it without knowing about the need for safety precautions.So, just as a school is unlikely to allow someone to work with thermite, which is well within the capacity of most children to put together, equally it should not allow anyone to do this with a lens larger than 30cm across. Working on this scale is withi one order of magnitude in danger, and that's far too dangerous to be allowed in a school project, sorry.
Hoping I can ask some advice from you fine people...In Cyprus I cant get white primer let alone a spray gun andpsi compressor etc. Cypriots here have hit off both wing mirrors for parking intheir (public parking) space. Scratched side of car for parking in their(public parking) preferred space, and the sun damage to bonnet and roof wasterrible. The guy I bought the car from used a cheap scratch hider so about amonth later all these scratches came up... Anyway car doesn't feel great and none of this was any faultof my own so took matters into own hands. Wanted to know if a normalnon-professional could pick up spray cans and revitalize his car. Here's how Igot on:Today went to check on car and some Cypriot guys shouting atme to move the car. Then noticed the same guy had stolen my new polishingcloths and scrapers etc... I just smiled.So far: Tape car -> prime car -> paint white on primer-> sandpaper drips -> paint white until drips gone. No clear coat, no buffing, no rubbing compound, no wetsanding... just primer and 27 cans of white gloss and lots of care andattention. My problem is I have shadows of white despite having a thickbase coat. Probably just because its an outside job and spray paint in wind etcisn't great. Should I use a thick foam block by hand lightly skim the topsurface with rubbing compound, then buff and clear coat? Or wet sand, then buffand clear coat? I've never wet sanded before and doesn't feel right on a thickbase coat...
Hello, thank you so much for this experiment! My sister really wants to step up her science fair game and we are thinking of doing something like this. Do you think that we could melt a penny (or anything) with just the fresnel lens?

Dont throw away they TV itself. The rear projection tv's have three tubes full of a bunch of lenses, long focal point, short, convex and the like. very high quality optics too, good for refractive telescopes.
