The Chemical-Free Chemistry Kit 296

Posted by Soulskill from the think-of-the-increasingly-stupid-children dept.
eldavojohn writes "It's known that home chemistry sets are in danger of going extinct, which has spurred set makers to add the label 'Chemical Free!' on modern chemistry sets (NSFW warning — JAYFK stands for Journal of Are You *expletive* Kidding). The kit for ages 10+ provides 60 chemistry activities that are mind-bogglingly chemical free. The pedantic blog entry points out the many questions that arise when the set promises 'fun activities' like growing plants and crystals — sans chemicals! That would be quite the feat to accomplish without the evilest of chemicals: dihydrogen monoxide. While this rebuttal is done in jest, this set's intentions do highlight the chilling growth of a new mentality: Chemicals are bad. Despite their omnipresence from the beginning of time, they are no longer safe. Even real researchers are starting to notice the possible voluntary stunting of science education that is occurring in the name of overreaching safety."

    Laugh all you want, but that stuff is a powerful solvent that's highly reactive. It can promote corrosion in metals and bacterial growth, is used in making many deadly compounds, and even becomes explosive when mixed with common chemicals like sodium. I hear they're even spraying it on houses and cars now to strip away dirt and grease. It's THAT powerful a solvent. All that and yet our kids are exposed to the stuff every single day, and no one seems to care. These our OUR KIDS we're talking about, for christ's sake!

      Alright, I can't take it anymore. Even in the absence of a "common" name, I doubt that any chemist would refer to H20 as "dihydrogen monoxide", any more than aluminum oxide (Al2O3) would be "dialuminum trioxide". It's redundant, people. We call H2O2 "hydrogen peroxide" -- not dihydrogen dioxide -- and "hydrogen oxide" is all you need to distinguish H2O from that. If we're being pedantic, that is.

      • Thank you. As a chemist, I often have to fight the urge to punch somebody in the face when they say "dihydrogen monoxide" or similar nonsense names for water. Don't use your own ignorance to try and illustrate somebody else's.

        It depends upon the nature of the bonding in the compound. For ionic compounds (such as your aluminium oxide example) numerical prefixes aren't used, as the charge of the two ions determines the ratio of them.

        Covalent bonds don't work the same way. For instance you could have either Carbon Monoxide (CO) or Carbon Dioxide (CO2), so the information of how many oxygen atoms present is required to correctly identify the compound. In these cases, because carbon comes first, we don't need to specify monocarbon- as that is assumed by convention. In the case of dinitrogen tetroxide (N2O4) the di- prefix is used for the first word.

        Water does of course present a little more of an interesting challenge, as it can be seen as many types of compounds. It can be seen as an ionic compound (where you'd call it hydrogen hydroxide), or as an acid (which would be hydroxilic acid), or as a covalently bonded compound. Oxygen dihydride may be the /more/ correct way to refer to it as a covalently bonded compound, but as the convention is to write the formula as H2O rather than OH2, I'd stand behind dihydrogen monoxide as the correct name.

        Yes, IAAC.

Due to the magic of profiling, I soon had a full dynamic entry from the DEA to add to my list of interesting experiences. That alone makes a real chemistry set dangerous as hell -- those guys were within a twitch of shooting us! They looked and acted a lot more like the meth heads they thought they were there to "Take down" than any real meth head I've actually met. Maybe they were hoping for a free fix.

They were fine with that once they sent the BATF out to check. And weirdly enough, it was the BATF who were nice and polite, no drawn guns, we had a fun talk and all. Maybe, unlike the FBI/DEA/DHS, they bothered to actually look up my dossier and find out I was an ex-spook with a long record of exemplary government service -- for the "good guys", so they treated me with respect instead of disdain.

When I was five or so, he gave me a bunch of lab-grade equipment to use as I please: beakers, Petri dishes, test tubes, a rack for them, cleaning equipment, graduated cylinders, glass pipettes (the kind they use in a real lab, with precise markings), the works.

    It wasn't before long that the carpet in my bedroom had several stains and outright holes around the part where I played with the stuff. I mixed up all sorts of crazy stuff: glue from vegetable oil, some green acid that ate right through the carpet, and some sort of caustic foam from god knows what components comes to mind. My parents didn't mind it that much, because was learning. My father didn't even bat an eye when I took a mouthful of that green acid because I couldn't see it creep up in the pipette, he just told me that I should do that facing the light so I can see it. The caustic foam got all over my hand, yet my parents weren't suing anyone.

    I was barely ten when I helped him develop film in the lab. If anyone did that before, they know that the stuff used is not kid-friendly, and can kill you in a heartbeat. Why didn't I die? Because I didn't fuck around with them. I did what my father told me to do, and didn't do what he told me not to do. I also had the common sense to approach stuff cautiously. I don't try stuff that looks dangerous just to see what happens.

    There's probably a lesson in here for what appears to be the majority of American parents: kids need their freedom. Why not let him endanger himself a bit, just enough to teach him that it's not good. The more sheltered a child is, the less likely to be able to cope in the outside world. If the kid is allowed to explore and learn on its own, it'll become that much stronger and adaptable. Thus, removing 'dangerous chemicals' from a chem set is not the answer, nor is absurd supervision. The answer is to teach him properly.

  • My wife bought a Chem set for my then 3 (now 4) year old son several weeks ago. After doing the relatively simple experiments he went around saying he wanted to do chemistry when he grew up for almost 2 weeks. Monday they did a second set of exeriments (creaitng a hydorscopic crystal from the results of the 1st experiment) and he got JUST as excited.

    And now that he gets to see the 'mushy' crystals after they have absorbsed water in the air is is almost giddy.

    There are still ways to teach our kids. Really we
