A couple come to mind.

 

Instant Coke which is an iodine/starch clock reaction.  Very cool.

 

Elephant toothpaste which is messy fun.

 

And my personal favorite - instant fog BLEVE (boiling water into tub of LN2 - demonstrator will get wet but it's impressive).

 

If you want the write-ups, let me know.  None of them generate hazardous waste or fire.  We do them in our outdoor courtyard all the time.

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.
