Chemical Reaction A chemical garden created by dissolving Cobalt Chloride in a Sodium Silicate solutiongiphy.com
I'm a chemistry teacher at a gymnasium in Sweden and for this semester I wan't to do more demonstrations for my students to get them hooked on chemistry, especially in the beggining. We don't have large fume hoods (unsure about translation), only smaller one without the option to close it up and neither do we have the option to do experiments outdoors so I'm pretty limited in what I can do but any tips would be appreciated.
Edit: Thank you so much for the replies, I'll look into all of it. Amazing community
