Cu-Al tradeoff demo: strips of aluminum pie plate in copper chloride solution produces copper & AlCl solution with color change. Takes time but you can do other demos while it runs.

I like the lit magnesium strips inside of a block of dry ice about 1 ft on a side.  Slice it in half (easy) and hollow out a center section.  Put Mg in center and put top back on.  Turn out lights and it will light any auditorium as the Mg burns from the oxygen of CO2.  Very Cool, low hazard with modest ventilation needs.

1 L graduate filled with a variety of pH indicators - drop in solid dry ice to get bubbles and lots of color changes.  You can also check out Shakashiri's 3 books of great demos, including a wide variety of clock reactions that don't require hoods.

I think the nylon rope trick is amazing. Isn't that relatively low hazard? - Pete Reinhardt, Yale

Hello All,

 

Our Chemistry Dept.  has a community night, were they do demos.    Typically, this has taken place in a lecture hall with a demonstration fume hood.    Recently, our new science building came online, and the coordinator of this community night would like to do the demonstrations in a public atrium area.    I'm looking to the collective group for help.   Do you have a demonstration that is low hazard, but HIGH cool factor that could be an option?   

 

If you would like to contact me offline, my email is jghamo2**At_Symbol_Here**email.uky.edu.

 

 

Thank you so much for your help.
