Looks like the Russian Army has opened up another front in Eastern Ukraine near the city of Kharkiv, either as a second attempt to capture the city or as a diversion to force Ukraine to move their forces away from the fronts in the Donbas region or the approach to Odessa. How do you think the...

Apparently this happened at a fireworks festival. Not sure why so many people had green lasers, or why they all thought this was a good idea, but when an airplane flew by the event a whole bunch of people thought it would be a good idea to shine their lasers at it. :mad...

Happy Valentine's Day everyone! :cool:

Some new pics of my collection which now features the 561nm pen from Tinkertavernco! :cool: As expected this colour doesn't photograph well, but I did do some comparison shots anyway. From left to right: 450nm, 488, 532, 561, 595.5, and 650. The camera does pick up some differences in the two...

I just ordered a 561nm pen from tinkertavernco's sale last week and was wondering if anyone else had tried this. Many digital cameras have trouble with certain wavelengths, often with lasers in the 405 and 540 - 580 part of the spectrum. Many pictures of them appear the wrong color and not at...

Saw this fleshlight at my local Canadian Tire store a few months ago. I didn't really need it, but after going past it a couple times while there for other things I eventually caved and bought one. After of course testing it out in the store by looking right into the aperture and activating the...

Was looking at some model railroad stuff on eBay the other day and I saw a train set called a "laser train", but very disappointingly, it had no real lasers on it whatsoever! So I decided to create a real laser train with my model monorail and the J Lasers 1.6W 450 and 700mW 520 lasers. :cool: I...

Lot's of interesting things going on around the world, so going to try this again with a slightly different approach. For discussion of all news, not just political, from local disasters to world wars (hopefully not lol). Let's just try to get to page 10 this time before this ends in a...

Happy 4th of July everyone! 🎆🎇🎆🎇

Some random pics I took today of my lasers. Used a little bit of fog, but not much was needed as we still have a lot of nasty smoke from the forest fires here in Canada. My rainbow: (left to right: 5mW 635 from Z Bolt, ~5mW 593.5 from Techhood on eBay, Laserglow 5mW 532nm Lyra, Sanwu Pocket...

I'm sure pretty much everyone here in Eastern North America has experienced at least some of the forest fire smoke in the last couple weeks. We have several large fires burning in Quebec just a couple hundred kilometers north of where I am in Ottawa. Really terrible to be outside in this, but it...

Happy Year of the Rabbit everyone! 🐇🐇🐇🐇🐇🐇🐇🐇🐇🐇🎆🎆🎆🎆🎆🎆🎆🎆🎆🎆🎆

Just saw this video from Chemistry YouTuber NileRed today. I think a few people on Science Madness got to making trithioacetone, but none ever showed any pictures or videos or went as far as cracking it into actual, legendary, thioacetone. :ROFLMAO: 🤢

Apparently scientists at the Lawrence Livermore National Laboratory achieved this crucial step in the path to nuclear fusion energy. The NIF reactor uses a massive laser to confine and ignite the nuclear fusion reaction, unlike the magnetically confined plasma in many other fusion experiments...

Anyone going to try and watch the lunar eclipse tomorrow morning? If I manage to wake up, I'll try and take a look. :LOL: Hopefully I'm not so tired that I clumsily drop my telescope right off the mount and it smashes. :ROFLMAO...

These lasers are two awesome new additions to my collection, they are the JLasers 700mW 520nm and the 1.6W 450nm. They come in these amazing looking chrome hosts and use a single 14500 battery. Very solid high-quality host, up there with some of the high end LaserGlow portables I own like the...

Just saw this video today, an astronomer's worst nightmare: a MASSIVE 14" cassegrain telescope tumbles right off the mount and SMASHES to smithereens!

A few pictures of my Uranium element cube. First by itself, second was under a 365nm LED light, third was with my 395nm LED light, and the last was with a ~15mW 488nm laser.

Hopefully numerous pumpkins blown up and houses ostrich egged! :D
