Jessieee Posted October 17, 2004 Posted October 17, 2004 well... we need to do some sort of project work on the topic household chemistry... it includes experiments, reports, investigation etc... i wanna get some new ideas... which means those hven't been done by someone else... not those common ones i mean... n better hv some actual applications, it may not be a well developed one tho... em... any ideas? =)
Jessieee Posted October 17, 2004 Author Posted October 17, 2004 well... actually the project aims to develop our creativity or some sort of problem solving skills..so it doesn't hv some precise rules actually..
Gilded Posted October 17, 2004 Posted October 17, 2004 Make a fragment grenade using some bolts, drain cleaner, aluminum foil, an empty soda can and a torch of some sort.
boris_73 Posted October 17, 2004 Posted October 17, 2004 LOL but you made a mistake that only works with sulphuric acid drain cleaner but other wise good idea
Gilded Posted October 17, 2004 Posted October 17, 2004 Doesn't it have to be alkaline drain cleaner, not acidic?
budullewraagh Posted October 17, 2004 Posted October 17, 2004 when i asked about restrictions, i knew that people were going to talk about things like the above. in terms of safety, how safe does this have to be?
Gilded Posted October 17, 2004 Posted October 17, 2004 Safety is, of course, a very important factor when doing just about anything (especially when spending a night with a Russian prostitute j/k ). So, perhaps if you would give rough borders for the experiment, then we were able to serve you better. :>
Jessieee Posted October 18, 2004 Author Posted October 18, 2004 actually i think we hv limited resources n apparatus, just those commonly found in the lab(not a very professional one of coz..=_=") em... abt safety... i think...... as long as we wont reli get hurt or sth will be ok..=_=" and those experiments will be carried out in the school lab, so.... i think it can't be too dangerous... or else it will be banned...haha...
Gilded Posted October 18, 2004 Posted October 18, 2004 Perhaps the bomb I talked about is more of an outdoor activity than a lab experiment. "actually i think we hv limited resources n apparatus, just those commonly found in the lab(not a very professional one of coz" Hmm... Could you perhaps give a rough list of the chemicals/tools available?
Jessieee Posted October 18, 2004 Author Posted October 18, 2004 well... lol... actually i am not very sure abt that... =________=|| maybe i should think of some topics that i would like to do n see if it's workable or not.. actually it need not be a complicated one, as long as it's creative n worth doing(may hv some applications or so... sooo... just give out any idea, i will try to sort out whether i hv those resources or not maybe later... i got a long period for this project actually...
jdurg Posted October 18, 2004 Posted October 18, 2004 You could do the generation of pure chlorine gas, and its reaction with a common metal like aluminum or iron? This can be done by taking a vessel and putting some Calcium hypochlorite (Pool chlorine super shock) or Sodium hypochlorite (household bleach) into it, then adding a relatively pure acidic medium. (Like an acidic drain cleaner that just has sulfuric acid in it, or pool acid which is known as muriatic acid which is just hydrochloric acid). You would then have a tube coming out of this vessel going into yet another vessel, but this one filled most of the way with water. (This will clean out any acid vapors, or other contaminants). You would then have another tube coming out of the water flask (Above the water line) and going into a flask filled with dry sodium bicarbonate (Baking Soda). This will dry the chlorine gas. Finally, you'll have a tube coming out of that flask and going into a bigger collection flask. This is where the clean, pure, dry chlorine gas will accumulate. You'll be able to see it because it will have a faint, pale-green color to it. (If you put some white paper behind it, you'll see the color better). Once you've got enough chlorine, you can quench the reaction by dropping some lye into the generation flask. With your bottle of chlorine gas, you can put colored fabrics in there and watch them bleach, or you could put some steel wool in there and watch it catch fire as it burns in the chlorine atmosphere.
Callipygous Posted October 18, 2004 Posted October 18, 2004 Make a fragment grenade using some bolts, drain cleaner, aluminum foil, an empty soda can and a torch of some sort. how does one light said grenade without blowing ones hand off?
5614 Posted October 18, 2004 Posted October 18, 2004 you could take NH4OH (ammonium hydroxide - the common version of ammonia) and mix it with iodine, this makes NI3 - nitrogen tri-iodide, this is a touch sensitive explosive device which is not too harmfull, it only makes a small explosion and is perfectly safe for a lab. theres a whole thread on it here: http://www.scienceforums.net/forums/showthread.php?t=3176&page=1&highlight=NI3
budullewraagh Posted October 18, 2004 Posted October 18, 2004 actually, iodine is really expensive, nitrogen triiodide yields some really unpleasant gases and it explodes very violently if you do so much as breathe on it
jdurg Posted October 18, 2004 Posted October 18, 2004 actually, iodine is really expensive, nitrogen triiodide yields some really unpleasant gases and it explodes very violently if you do so much as breathe on it He's not kidding. I once set off a small pile of it by farting only about twenty feet away. Sure it was a low-bass, rumbling tooter, but I was laughing for hours after blowing it up with a fart.
r1dermon Posted October 19, 2004 Posted October 19, 2004 yeah, its good stuff. keep it wet and its perfectly safe. but clump it together and dry it, and dont touch it with a feather or BOOM. its fun to paint on the floor or a piece of toilet paper and then let it dry, and put it on the floor so people step on it...like little caps going off.
budullewraagh Posted October 19, 2004 Posted October 19, 2004 wait, doesnt the decomp yield iodine dioxide and nitrogen dioxide?? if so, that is NOT cool to breathe in at all lest we all get pulmonary edema and die
hyebeh Posted October 19, 2004 Posted October 19, 2004 if this is a creative experiment about YOUR creativity... why are you asking others for help? my idea: make thermite and demonstrate it's violent exothermic reaction.
budullewraagh Posted October 19, 2004 Posted October 19, 2004 if you do a thermite, use aluminum and lead dioxide, as it's much less dangerous
hyebeh Posted October 19, 2004 Posted October 19, 2004 or you could just discover a way to do cold fusion har har har
YT2095 Posted October 19, 2004 Posted October 19, 2004 why not something SAFE and Sensible instead, you could make a crude form of Plastic using warm milk and vinigar. there are other plastics you can make too with basic chems, copper sulphate, filter paper, ammonia and 1 or too others. all are safe and you can actualy say you`ve made you very own plastic!
Jessieee Posted October 19, 2004 Author Posted October 19, 2004 why not something SAFE and Sensible instead' date=' you could make a crude form of Plastic using warm milk and vinigar.there are other plastics you can make too with basic chems, copper sulphate, filter paper, ammonia and 1 or too others. all are safe and you can actualy say you`ve made you very own plastic! [/quote'] it's seems interesting!... as the topic household chem is rather "wide"... it's reli hard to decide what to do... n we aren't suppose to do those which we hv learnt... like Cl bleach... n... we need to do a series of experiments instead of one only... i mean... it's like an investigation or sth... for example... last yr they do "colour chemistry" some topics were... investigation og hair colourants.. how gd is red cabbage as a dye? natural colours as indicators n dyes acid-base indicators from plant materials vleaching of coloured substances by hydrogen peroxide analysis of polyphenols and colour of green tea ...
YT2095 Posted October 19, 2004 Posted October 19, 2004 no problem, We`ll have a think about it for you here`s a site about the plastic in the mean time: http://www.bayerus.com/msms/fun/experiment/milk.html
Sorcerer Posted October 19, 2004 Posted October 19, 2004 Hmmmmm kind of sick, and Ive had a few..... but how about... an alliterative title: Uses for Urine. speaking of which, I think I'll go clean that stain off the bowl.
