I am reposting this because I still haven't found the "best answer."
I have already done vinegar and baking soda, floating raisins, made a cornstarch suspension. The experiment has to be done in under 20 minutes and I can't use a stove or microwave. The experiments have to be nontoxic in case the students eat it.
It is for a General Science Special Education classroom. The experiment can't include toxic materials, glass, or fire. Again, I can't use fire, glass, or toxic materials in the experiment. It has to be done in under 20 minutes and preferably use materials that are easy to get.
