I do some of the common demonstrations that I recommend most do NOT do as demos. Using ‰??Whoosh bottles‰?? in a slightly different fashion with multiple accelerants to demonstrate the fire triangle, that it is the vapors that are flammable and not the liquids, etc. I think Flinn and Steve Spangler also have some for fire like the vapor ramp with candle and hexanes for showing vapors, grain elevator fires and how surface area makes things more likely to combust, and the hot pan to show how to smother a fire. I use eggs with sodium hydroxide to demonstrate that household cleaners can cause permanent eye damage. There are also universal indicators so that you can show how similar household items are to our ‰??chemicals‰?? regardless of how safe they think they are (We have moved to doing these as spot tests to reduce materials needed). I use chemicals on different types of gloves to show that not all PPE and not all chemicals behave the same. I do a lot with how to deter!
mine the hazards in common household items.
Actually, almost every demo I do these days has some component of chemical safety involved with it these days.
Caveat, I use chemicals that I work with ALL THE TIME and do these in controlled lab settings. Your venue also determines what you can and shouldn‰??t do.

Subject: [DCHAS-L] Established demonstrations for teaching how to use chemicals safely at home?
I'm wondering if anyone has an established program for teaching specifically chemical safety as part of their outreach activities? We have gotten requests to teach chemical safety as part of community "safety day" activities. e.g. meet with fire fighters, police, EMTs etc
This is not a request for how to do demonstrations safely, or common demonstrations appropriate for outreach audiences,å but rather what demonstrations are most effective for teaching basic principles of chemical safety to a young audience (K-12).å
Thanks in advance,
