Loose in the Lab with Genie in a Bottle

A cloud of hot steam rises from a 2 liter pop as we call forth the spirit of Mendeleev using his "cremated remains "(manganese dioxide) which are are dumped into the "spirit activator" (concentrated hydrogen peroxide). Water, oxygen, and a substantial amount of heat are released almost instantly and create the illusion that Mendeleev is rising from the bottle to join your chemistry class. Very entertaining, easy to do, excellent introduction to colloids, exothermic reactions or catalysts.

Safety goggles are $1 at the $ store. A box of 100 nitrile gloves run about $5. Go ahead and purchase both before you post any more videos. Concentrated H2O2 causes nasty burns on skin. Lawyers cause nasty holes in wallets and teaching licenses. Safety first. Youtube videos second. Teacher to teacher.
