I remember this happening to me in a chemistry lab at Wabash. We didn't got 45 minutes, of course, but I know that we kept thinking there should be a color change by 'now' based on the other titrations we'd done and adding a drop of phenolphthalein just to make sure.
The flask turned bright fuchsia, and we dumped out that trial.
I'll admit that Alec, the host of Technology Connections, might be a little more bothered than is reasonable about the harshness of blue and green LEDs during the holiday season, but he's at least trying to do something about it. (check the videos after the jump)
In this video, he celebrates the fact that a company is now producing warm white LEDs inside multicolored plastic (or maybe glass) bulb covers resulting in something more akin to the same colors as produced by the incandescent filaments inside colored glass bulbs of yore.
I do agree that the blue and green LEDs can be harsh, and the flicker can bother me at times - don't get me started on the LED bar light in my guest bathroom - but mostly I just grumble and move on.

But like every rule that humanity has come up with to describe the world around us, nature doesn't give even a little thought to following that rule. Nature does whatever nature does and our rules be damned.
As such, the octet rule is followed far more frequently that it is violated, but there certainly are compounds that don't follow the octet rule.
Now, as long as he doesn't make cherry coke from from scratch, too, we should be okay.
I love the idea of quasi-carbonating the sugar solution to trap unstable bubbles as it solidifies.
I also love that the large rocks of pop rocks look to be a little dangerous, actually.
I would absolutely eat that big rock.
This guy does a lot of things that I don't think I should do.
My wife has, admittedly, suggested that she might be interested in buying a freeze dryer. It's not something that's come up more than once or twice, but it's been mentioned.
Clearly buying a freeze dryer would be bonkers and nuts. We don't need it. The energy spent isn't remotely worth the very, very few times we'd ever use it before letting it sit unused in a closet somewhere.
At least that's my perspective on the thing, and clearly Mr. Technology Connections agrees with me.
Even though the science involved is kind of fascinating.
