This is good, cheap glow tape-Mark flashlights to find in the dark

I agree with you on everything.

We have gone off topic….but a bit on topic on the issue of safety.

We can agree you’re wrong if you believe EMF has any effect on health, unless psychological effects are what you’re talking about. The science is clear. If you choose to believe otherwise, you’re only throwing money down the drain and acting irrationally.

So-called “studies” that report otherwise are poorly done, use small sample sizes, don’t use proper controls, and resort to P-hacking to draw incorrect conclusions.

Non-ionizing EM radiation does you no harm, unless you’re flooded with so much of it that it actually burns you, like a microwave oven. You have to stand within a few feet of a large radio transmission antenna for that to happen. The inverse-square rule takes care of everything else.

There are plenty of real environmental hazards that can affect your health, without needing to make up others.

As for this glow-in-the-dark tape, yeah, I’d want to know what’s in it, considering how long it lasts. Normal GITD material is pretty dead after 12 hours.

PLEASE let’s not argue about matters of faith and belief here.

You can look this stuff up. Read past the first few hits from a Google search, and you’ll find the published science, which drops down the pages because it’s not what most people search for and want to read.

The key is to read past the stuff that echoes what you believe, which Google puts on the first page, and consider whether there are any sources that can change your mind. What you see is not what other people see. Google prioritizes sources you’ve preferred in the past, that’s the filter bubble.

Just asserting beliefs is, well, unproductive of any enlightenment.

Hard to believe how much I’ve learned from a thread about GITD tape :smiley:

Wellp, “established science” claimed the sun went around the earth (the Holy Center of the Universe, y’know), until that conspiracy-theorist and terracentrism-denier Galileo came along. The MSM of the time did its best to shout him down and relegate him to the fringes of society, too.

History is written by the winners.

So is “science”.

I did a little experimentation with some GITD tape & powder mixes.

First I thought I would try the heat method to charge these as I have noticed before a slight glow from these compounds when soldering stars that have it around the LED.

I applied various tapes & two powder mixes onto an aluminium plate and heated over a gas burner until they glowed.

Not too impressive after a few minutes.

Next I mixed up some glow powders with UV setting glue and clear silicone.
Charged briefly with an M43 XP-G2 3D on turbo for one minute.
The new LIT powder seems to glow best with a mix of 50:50 UV glue.

Here we have a comparison of the sticky tapes and two types of glow powder mixed with the recommended white acrylic base.
The glow powder mix was made very thick.

Interestingly, the much thicker white acrylic mix glows less after time than the thinner mixes of powder clear & silicone/ UV glue.
After the short charge time it is clear here that the LIT green powder mixed with the UV setting glue glows brightest after one hour.
I used approximately the same amount of powder in each mix.

Also note the cheap green glow sheet is brighter than the 3M 6900...

I think some more playing around with the ratios in the white acrylic mix is needed to determine if it is the best medium for the glow powders.

The LIT powder does glow with a little more intensity than the KillaBitz stuff to begin with but it is not revolutionary.

I must admit that I had high hopes of this stuff charging up by heat, imagine applying to a groove in the head of a light and having the heat charge up the glow - cool ;)

So I applied a little sample of each powder mixed with the acrylic base to the case of a little Nichia 219C triple hotrod to see what would happen. Wasn't quite the result I hoped for but like I said earlier I probably made the mixture too thick.

I might try some more thermochromic experiments too.

That ‘establishment’ was a religion, and ignored history.

Many still do: 1 In 4 Americans Thinks The Sun Goes Around The Earth, Survey Says : The Two-Way : NPR

Fluoride is good for you,

Radium-water is healthy.

Tobacco smoke is safe.

Cellphone radiation is safe.

Asbestos is safe.

How many things were “proven” to be safe… until they were later proven to be otherwise?

You don’t just make one too many cellphone calls and then suddenly develop brain cancers. It can take years if not decades to develop. And the body runs off electrical signals. So if hormones in the parts-per-million can screw with someone’s body and cause uterine cancer and the like, being bathed in weirdo EM radiation 24/7 won’t also screw with someone’s body in other ways?

If there’s even a chance it can, why ridicule someone for wanting to be safer?

After all, it’s not like scientific research can be bought funded by Special Interests, right?

The same way the Tobacco Industry bought studies for decades showing second-hand smoke was “safe”, you don’t think those industries involved in 5G or any other parts of the RF spectrum (including governments auctioning off slabs of that spectrum for fun and especially profit) would be unable to also buy research and studies showing that being bathed in EMR 24/7 is similarly “safe”?

Very true. Research today is driven by fund availability. Funding is driven by “interest”. And profit.

Please avoid controversial or divisive subjects such as religion and politics.

For example, bashing science as a whole is not helpful.

We as a human race wouldn't have made it far without science.

Mankind in general is pretty intelligent but at the same time we are to a retarded level unable to deal with chances, it is how our brains are designed. Direct proof of that is the wide existance and popularity of lotteries. Science unfortunately more often than not presents results as a chance of something happening instead of yes/no answers. Science can not do much about that because presenting a prediction as a chance that it happens is simply the closest to the truth. But our brains demand yes/no answers (“so there is a chance that it happens, therefore the answer is yes right?”,a or: “you guys are not completely sure about that so you must be wrong”), and then the goal of science to present the answer that is closest to the truth is crushed by our Neanderthaler inner brain.

Because when someone refuses to accept the scientific consensus, they may as well wear tin-foil hats around. Note that I say consensus, since there are always whackos even if the scientific community. e.g., “cold fusion”.

There’s no plausible method by which EMR can hurt you. That’s the issue.

There’s plenty of plausible ways that smoke in your lungs can hurt you. Just because science hadn’t studied it enough at the time, doesn’t mean that the science was wrong. It just wasn’t done, yet.

Science has been done on EMR. The only studies that have showed any negative effects were poorly run cell-phone radiation experiments, where they looked for correlation after the data was collected, i.e. P-hacking. And those results were just weird, like showing tumors in only one sex of rats, even though those rats actually lived longer. The conclusions just didn’t match the data.

Correlations don’t mean causations, especially when you go looking through the data for improbable effects:

ok my final comment on the original product is - i was wrong - it doesn’t glow forever

after about 4 days i can see the glow will be gone in about a week

( i was just assuming half a day [night] of glow meant it would go forever. but at least if it gets daily charging, it goes all night just fine, which is sort of the same thing munis the radium )

Are my posts invisible?

No, we are just being a bunch of unthankful jerks. :person_facepalming: :stuck_out_tongue: :smiley:

Thanks for that great investigation into GITD tape and powders, very useful!

Cool, thanks, just wondered :smiley:

That’s fine, an extra several hundred bucks is a joke “cost”.

I’ll stick to the science that tell us that cancers are caused by many things, some are unknown.

So if you eliminate as many as the knowns as possible, some of the unknowns that may never be known and some of the unknowns in case they become known, then chances are that I’ll live longer then my father who just sailed past 101….

Let’s say the probability of being shown unsafe is one in a million.

Is a few thousand dollars “better safe then sorry” upgrades in a house that will get close to 7 figures mean anything? People spend several hundred on a sexy sink that is below the countertop and will trap bacteria for decades. They spend thousands on elaborate columns that tells the world they are Neros descendants.

Neither here or there. Like I said to the builders, my money, my rules.

(BTW….you guys in the southern states are laughing when it comes to building costs. Up here it’s $250 ft2. Even breadboxes run $160 ft2. In USD, $190 and $120)

CRX, thanks for posting those results. Never thought to mix powder with clear silicone. I was more interested in your orange tape results, but that color seems to be the worst. I was going to purchase some orange tape to place inside a head rather than $40 worth of trit vials.

The silicone I use is this stuff which is more of a liquid before it sets, doesn’t have that acrid smell to it and sets relatively soft.
Yeah the orange & red colours are the worst performers, if you considered using trits then use those, can’t beat the vials.
Glow tape is nice for an afterglow but fairly short lived.
