- In this video we demonstrate the reaction that gave us the first spot light, and the phrase "in the lime light".
EDUCATORS - Feel free to use this video in your classes! That's why I started making these.

I enjoyed the lame lime joke. Thank you. Fun fact: when theaters had several of these going it could eat up the oxygen in the theater giving everyone a headache. Fun!
Same, I was kind of skipping through just to see the effect of the light lit up. And then I saw the prop joke and I was like, 'Oh man, there were jokes in there? I thought this was going to be totally dry"
I think you meant the lame lime lime lime light joke. ;)
I’m reading a book about an old theater in centuries past and this helped me understand how limelights work SO well! Thank you!!!
The humor in this video was hilarious, and the science was on point! Love it!
Somewhere sometime in the not too distant past (within a few years) I saw a video of a demonstration of a limelight fixture being lit and fully demonstrated. Tried finding it again to include in a workshop and can't find it for the life of me. I am sad. But this was great! Thanks!
please drop it here, if you have found it
The bottle constantly changing about killed me, Great video in general and very informative!
Thank you for this clear and concise video, especially the proper meaning of limelight. I came here via a short story written by Lucretia Hale entitled THE PETERKINS' CHRISTMAS TREE. Published in 1886, it narrates the antics of a quirky family in their quest for a proper holiday tree with all the trimmings. Quoting from the tall tale here: "Agamemnon wished there was time to study up something about electric lights. If they could only have a calcium light!"
I guess that's better than candles, but it still makes my inner fire safety person break out in a cold sweat.
I enjoyed this video as I’d gotten curious about what a limelight was and what it looked like. Likable, entertaining, and knowledgeable presenter!
Awesome video.
I learned "lime light" existed after watching a video about a Civil War time Area 51/munitions factory in Columbus, Ohio. It was lit by limelight, as electricity wasn't available.
Oh that sounds like a bad idea.
a scientist AND a theatre nerd. Love it!
This was rad! The space shuttle example made total sense, and I had no idea that it was that much brighter than a flame.
I wonder if the light would be more brilliant if it was heated up longer, or if it was a larger piece of it (the drawings I saw seemed to use a big cylinder of quicklime). Either way, still very impressed - thanks for sharing!
Thank you for this perfect demonstration of what the limelight is. I was reading the book "At home by Bill Bryson" in which he speaks of this type of light. Eager to see what it looks like. Glad that there are people like yourself sharing this.
Greetings from Amsterdam
That lime joke was excellent! I'm adding it to my collection of dad jokes.
very informative, and highly amusing...lighting a lime with a lime filtered lime light..love it!
Shout out to those of us who genuinely smiled at the lime in the lime lime light joke.
Great small video of former used technologies. Very impressing the difference between flame only and limestone. Love the flat yoke with the lime, lime light lights a lime😂🤣👍🤗
Great video, very explanatory. I also loved your sense of humour throughout the whole process. Great work
That was cool, start to finish. Thank You for explaining!
Thank you for demoing this! I was very curious to see how it looks.
Thank you very much for this demonstration!
you earned my sub for your great humor
Your terrible joke is the reason I subbed (and the science of course)
Wonderful video and great explanation, thank you very much for making this!
You deserve way more subs. Excellent video!
Wonderfully done
Was looking for this info, thanks!
This is actually really sick.
Let's bring these fire hazards back!
I didn't know anything about lime light before. Such interesting explanation and demo, with a few "dad jokes" here and there.
Awesome Video
That was very informative oh, and you are very funny. Thank you very much for your presentation.
Excellent video! Make more!!!
This was very informative and hilarious, thanks!
Thank you for the explanation
Great demo!
I thoroughly enjoyed the demonstration. Reminded me of my teachers on high school :)
Great demonstration! I wonder if the hiss of the torch was distracting in those theaters...
Amazing
thats awesome, thanks
Thank-you!
Maybe the best video on the internet.
Wow.... That last footage reminds me a lot to chiaroscuro paintings
So I am guessing they had hydrogen from coal gasification and a bellows to feed the flame, thank you for this.
6:14 🤣Excellent joke, thanks for the demonstration.
I like the little continuity error on the do not drink water bottle lol
How are there no comments on this? Your humor is adorable.
Because I only just found out that I wasn't getting notified that there were comments held for moderation! Yay!
Wish I had became a chemist instead. Looked way more fun to experiment with the elements but also had to be careful not to get yourself in trouble
that was actually an amazing joke
you have my Ikea lamp on your desk!
😃😃
Thankyou
Internet Historian brought me here!
Of down the theatre this evening to drive the modern 1200W HMI equivalent.
The modern term is Follow Spot Operator , used to be Lime Op. And in Victorian times when it was a 'Lime Light ' you would have been a 'Limelight Turner'
As ever nobody notices you unless of course ' you get it wrong!'
I did much appreciate your continuity error water bottle
wow thats impressive how much it lights up compared to just the flame. its like evening and night difference XD
Really enjoyed the demonstration. Was expecting you to then drop the lime in a coconut. Oh well.
I like watching the process from very beginning to the very end. The only problem with this video is where you got the quicklime / limestone. Thanks for video.
I bought a limestone tile at the hardware store.
@@jonathanbastow3538 Yeah I know. If you went out and foraged for it. It would have made it that much better.
You're funny
Lighting a lime with a lime lime light 😂🫶
Can you make this from ground up seashells?
I have no idea! Maybe?
@@jonathanbastow3538 ok, I heard of someone making limelight at their beach house. Thanks 👍
Fell down the Wikipedia rabbit hole and ended up here.
I have no regrets =*-*=
After the modern electric light is on:
- Where is my Hair???
I came for the Science
I liked it for the Comedy
not to be that person but, your lil example of what an old gas light would have looked like is inaccurate when it comes to the amount of soot, yes soot particles were very much part of the system, but you wouldnt see that as trailing black streaks of smoke, the flame would have been on a burner specifically designed to ejaculate the gas to maximize light and flame size and would be steady, only interrupted if a draft from an open door bothered it or someone else lit another gas light on the same line, miniscule amounts of soot would have been enecred constantly without the user noticing, and only suddebly realizing a week or so later that the walls have been darkened
I'm having a hard time finding a measurement of the brightness of limelight
Unfortunately I didn't have a light meter when I made this video. I've got one now, I should probably do a followup.
@@jonathanbastow3538 that would be cool. I'm thinking the best non electric lighting source for local sourcing would probably be wood-gas torches with gas mantles. But I'm also curious about limelight. I wonder if it would be possible to grow plants through the low light conditions of a northern winter that way
that was a terrible joke and i hit like
Are we not gonna acknowledge the water bottle that's attempting to communicate to us?
Lighting a lime with a lime limelight, now if you were say brittish....
I am half Limey.
@@jonathanbastow3538 Blimey!
..... But I'm not!
Bro you got potential. You just need to work on your script 🤦♀️😂😂
Your terrible joke had a lot of potential if you took it with a more theatrical vibe
Have you ever thought of being a writer?
pls no more dad jokes
NEVER.
I Just Looked Into That Mapp Gas Thing You Said ANd Yes, It's Totaly True, All Production of Mapp Gas Is Haulted.
In early 2008, true MAPP gas production ended in North America when production was discontinued at the only remaining plant in North America that still manufactured it. However, many current products labeled "MAPP" are, in fact, MAPP substitutes. These versions contain mostly propylene with some propane, dimethyl ether is included as a 3rd ingredient in some versions.
Fun video!
Curious... is the heating of the limestone stinky? Did it crumble apart? I see that on original designs, there was a screw system to continually raise the lime much like a wick in an oil lamp.
So... is it "consumed" rather quickly?
It didn't smell, and did crumble a bit. I was only doing this for a short time, so I could absolutely see one being used for hours needing some method of adjusting it.
@@jonathanbastow3538 Interesting. And the oxyacetylene? I assume THAT is needed for proper chemical reaction and/or heat level?
Considering a demonstration but only currently have access to a propane torch (for plumbing soldering, etc.)
Thoughts on if that might work?
Thank you for your time.
