glucose in passover coke?
From Reactions. If Passover Coke is made with cane sugar instead of high fructose corn syrup, then why is glucose present? #passover #cocacola #glucose
Why Norway’s Osmosis Power Plant Failed
From Reactions. Check out Weathered and the PBS Earth Month Playlist: When seawater and freshwater mix, a surprising amount of energy is released. Norway tried to capture this energy using an osmotic power plant, but the plant mysteriously and abruptly shut down. Join George as he tries to figure out why using dialysis tubing, toilet…
my dog ate an entire box of packing peanuts
From Reactions. cornstarch packing peanuts are not food grade and shockingly not delicious. you’d probably be fine if you eat them, but don’t. #cornstrach #packingpeanuts #styrofoam
Hot Water Freezes Either Faster or Slower Than Cold Water
From Reactions. The Mpemba Effect happens when hot water freezes quicker than room temperature water, or does it? Alex goes on an exhaustive journey to replicate the Mpemba effect and hits a few snags on the way, including a paper being released the week this video was supposed to come out. Does this paper finally…
there’s a surprising amount of fluoride in tea
From Reactions. And don’t get me started on fluoride in drinking water. Seriously. Please don’t. I already made an entire video about that, I can’t handle any more. #fluoride #tea #chemistry
it’s called “heterogeneous nucleation”
From Reactions. and if you’ve been paying attention to our other shorts, yes, this crystallization is also how those hand warmers work #chemistry #crystallization #sodiumacetate
don’t swallow watch batteries
From Reactions. a watch battery stuck in a hot dog creates what looks like a chemical burn but what’s actually happening is electrolysis. don’t let your children eat button batteries. #electrolysis #chemicalreaction #batteries
Why a Carbon Capture Breakthrough Will/Won’t Save Us
From Reactions. Chemists have been pulling carbon dioxide out of the air for almost 300 years, but can this seemingly magical technology save us from climate change? George answers that question with a couple of Erlenmeyer flasks, some limestone, two envelopes, and a straw. Producers: Andrew Sobey Elaine Seward Darren Weaver Writer: George Zaidan Hosts:…
here’s how those hand warmers work
From Reactions. it’s cold so warm up with some science #handwarmers #sodiumacetate #iron
What the Research Actually Says About Fluoride in Drinking Water
From Reactions. Fluoride has been all over the news lately and people with PhDs can’t agree on if it should be in water or not. We wanted to get to the bottom of this controversy. Alex went on a mission to find out once and for all what the research actually says and what the…
gel tab goo turns white when you swallow it
From Reactions. drug solubility also played a key role in the ritonavir near-disaster in the late 90s, which we talked about in our latest episode. #medicine #chemistry #macro
getting (some) bismuth out of Pepto Bismol
From Reactions. Going to have to get that yield higher so I can grow some proper bismuth crystals at home. That can be another video. #experiment #chemistry #medicine
How an HIV Miracle Drug Vanished
From Reactions. In 1998, a pharmaceutical company suddenly lost the ability to make their lifesaving HIV drug at one of its production facilities. Then that failure spread to the company’s analysis labs. Then it spread to the other production facility, and within months the lifesaving drug had effectively vanished from the entire planet. And this…
stop it with the CaCl2 in canned tomatoes
From Reactions. Seriously why do they add it? Who wants this? #tomato #foodchemistry #calciumchloride
tempering chocolate is chemical engineering
From Reactions. Why might someone undertake this incredibly exacting task? Well because tempered chocolate is firm, snappy, and pretty. #chocolate #chemicalengineering #crystalstructure
why cane sugar vs HFCS in a soda doesn’t matter much
From Reactions. You can probably taste the difference between Mexican Coke and the US version, but it’s probably not because of cane sugar vs. HFCS. #coke #sugar #chemistry
the internet was wrong
From Reactions. Special thanks to University of Maryland’s Department of Fire Protection Engineering for letting us join in on their annual Christmas tree burn. #experiment #borax #fireproof #stem #christmastree
The Internet Was Wrong About This
From Reactions. A common internet recipe claims to help fireproof your Christmas tree with borax… but the Reactions team was skeptical. We set out to test the best ways to keep your tree safe, with the help of some fire scientists at the University of Maryland. Along the way, we set some trees on fire…
Everyone is Wrong About Mexican Coke (Even @johnnyharris)
From Reactions. Check out Pan Pals on PBS Food: https://youtu.be/BWxJPOUkH9Q?si=bdp86-n6xFYjCZAZ A 2011 paper found that Mexican Coke – which is supposed to be sweetened with cane sugar – contained no cane sugar. Instead, the paper found plenty of glucose and fructose: the main ingredients in high fructose corn syrup. Could Coke be lying to us…
burning steel wool in pure oxygen
From Reactions. The crazy part is even though the steel wool looks smaller, it actually weighs more than it started. #steelwool #combustion #experiment
i centrifuged different coffees ☕
From Reactions. I do not recommend. #centrifuge #experiment #coffee
Ti-dyeing (get it?)
From Reactions. Good old titanium anodization at its finest. #titaniumanodization #electrons #titaniumdioxide
Bredt’s Rule was broken
From Reactions. What’s more fun than proving a 100 year old chemistry principle wrong? #bredtsrule #molecules #chemistry #doublenonds
Does Lemon Juice Prevent Kidney Stones?
From Reactions. Take PBS’ audience survey: https://to.pbs.org/2024SurveyReax Kidney stones are the worst so I made some at home and tested supposed prevention methods to hopefully keep them at bay. Citrate is what doctors recommend to prevent them but how is a little lemon in your water going to stop them from forming? And are all…
