Rainbow pH demos can be done large scale.  One that always gets big applause is when we use Yamada indicator in a long tube and add a base at one end and an acid at the other and mix to get a rainbow.

 

 

 

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.
