Changes in Internal Energy, ΔE	Thermal expansion of gases	Dry ice is placed in balloon, plastic bag or rubber glove and sealed, then with time inflates the object.	It usually won't explode the balloon, but might break the seal on the bags to give a pop sound.  Also on Shakashiri tape 2 #29	30	Demonstration
Changes in Internal Energy, ΔE	Thermal expansion of gases	Dry ice sublimes and inflates the container.	Shakashiri tape 2 #29	M8	Movie
Enthalpy	Reaction of carbon/iron and oxygen	oxygen in a balloon is released into a beaker, a heated piece of iron wool or charcoal flames in it.	To be done in hood.	11	Demonstration
Enthalpy	Dehydration of sucrose	Dehydration by sulfuric acid.  Powdered sugar and conc. sulfuric acid makes snakes.	Little noxious due to sulfuric acid fumes being spewed a little.  The black carbon snake can be very dramatic out the top of the beaker.  Also on Shakashiri tape 2 #27	21	Demonstration
Enthalpy	Reaction of sugar/potassium chlorate.	This is better done outside.  It can be used to spell out letters in fire on pavement at a school circus.	Sulfuric acid starts the reaction.  Also see gummy bears #24.  Also on Close up on Chemistry Ealy 22:10 (2:11 min)	22	Demonstration
Enthalpy	Torching gummy bears	The potassium chlorate is melted in a tube, and the gummy bear dances and growls as it is consumed by its combustion, sparks shoot inside the tube and it is bright in the room.  Do outside if the room is small.	A very popular demo for sacrificing for football or test success.	24	Demonstration
Enthalpy	Endothermic reaction of barium hydroxide and ammonium chloride,	The two solids are mixed in a covered flask and produce a smelly liquid that is cool to the touch when passed around, and that can make the flask stick to a wet board.	also for speed of smell.  Also on Close up on Chemistry Ealy 19:54 (2:16 min)	34	Demonstration
Enthalpy	Starch-iodine clock reaction	variations-temperature and concentration; variations of clocks containing starch only	Popular-can time or have a race, can explain the variations by reaction rate.  Also on Shakhashiri tape III #44 and #45	40	Demonstration
Enthalpy	Dehydration of p-nitroaniline:  Snake and puff	do outside. For inside, do #21 sugar and sulfuric acid snake		78	Demonstration
Enthalpy	Catalysis of H2O3	Sprinkle manganese dioxide into a beaker containing hydrogen peroxide on the overhead projector.  By using a small amount of catalyst you can see bubbles slowly evolve, or by adding a lot, the reaction is more violent and spews steam and H2O2 onto the head of the projector.  Exothermic reaction	For other catalysts see #43.  Can do this one as "genie in bottle" - do reaction in 2L Coke bottle, see bottle shrink.  Also on Shakhashiri tape III #48; Close up on Chemistry Ealy 31:03 (3:28 min)  (For Ealy set timer to zero when first text rolls on screen.)	96	Demonstration
Enthalpy	methane bubbles, snake charming	bubble methane gas through a funnel of soapy water to make bubble snake to light		141	Demonstration
Enthalpy	Calcium oxide with water, other exothermic reactions	Behind a shield add water to fresh calcium oxide, stir quickly, put on the egg in a watch glass, stand asside while it erupts, possibly breaking the beaker because of the heat produced.	A messy demo that can get out of hand.  Also see #167 for exo self heating meal, and #106 for sodium acetate	146	Demonstration
Enthalpy	Self-heating meals	edible demo, shows the exothermic iron rxn		167	Demonstration
Enthalpy	Thermite reaction	Not available - may be able to do in a hood, outside, or tape demo for use in class.	Outside.  On Shakhashiri Tape 2 #25	25.x	Demonstration
Enthalpy	Endothermic reaction of barium hydroxide and ammonium chloride,	The two solids are mixed in a covered flask and produce a smelly liquid that is cool to the touch when passed around, and that can make the flask stick to a wet board.	Close up on Chemistry Ealy 19:54 (2:16 min)  (Set timer to zero when first text rolls on screen.)	M12	Movie

Thermo, General	Explosive reaction of hydrogen and oxygen (balloons)	Hydrogen alone gives a swoosh and boom, hydrogen:oxygen 2:1 is very loud with percussion (you feel the explosion)	Also video on Shakashiri tape 2 #20 and #21	8	Demonstration
Thermo, General	Methanol Cannon	Combustion of ethanol or methanol in large cooler bottle.  The methanol burns with a swooshing sound out the top of the bottle, and may show "Northern lights" at the end.	Also shown on Shakashiri tape 2 #22	17	Demonstration
Thermo, General	Chemiluminescence	DMSO, KOH, luminol shaken for reaction, or longer lasting solution in COOL sign.  Chemicals are mixed and glow in the dark.	The potassium hydroxide version can be carefully passed around and shaken.  The cool version is good for chem circuses.  Also on Shakhashiri tape 1 #5 oxidation of luminol; Close up on Chemistry Ealy 26:36 (1:45 min)	27	Demonstration
Thermo, General	Nonburning money / hand on fire	50:50 EtOH:H2O  The ethanol solution is poured on the table and lighted, the hand is plunged down into it, displayed on fire, then waved to put out the flame.    The bill or towel can be soaked and "burned" but it isn't consumed.	Always practice first to be sure the solution is still good.	29	Demonstration
