I created this Halloween story my first year of teaching. Having recently been to a local American Chemical Society chemical educators' discussion group meeting, I found out about a clock reaction demonstration called "Old Nassau," and wanted to find some way to use it in my classroom for some sort of Halloween demo. At about the same time, my district mentor had loaned to me a book by Tik Liem that was full of demonstrations. After about three days of thinking I ended up with the story that is outlined below. The story and riddle are original, the demos are borrowed.
My third year of teaching found me in a new school district. The administration registered me for the ACTIVE Chemistry Mentoring Program* at Miami University, Middletown, Ohio. Our first two-day weekend meeting in early October, 1999 was centered around the topic of "Dynamic Demos." It was during this meeting that I shared my thematic Halloween story with the other teachers in the program. Many of the teachers used my story for Halloween; some of them modified it to their own liking. (You will find two of the modifications included below.) As representatives of the ACTIVE Chemistry Mentoring Program at Miami University, we presented a modification of my original story at the 2001 Annual Meeting of The Science Education Council of Ohio, on February 15, 2001, at the Convention Center in Cincinnati, Ohio.

The basic points of this story will work with the attached demonstrations very nicely. However, this story will only be as good as you make it. Adlib, personalize, and elaborate to the best of your abilities. The props you use with the demos will definitely enhance the story, as will your dress for the day. Moreover, I usually have a 2 liter graduated cylinder bubbling on my demonstration table to one side, and a large, black, plastic cauldron bubbling to my other side. They both are filled with water, and have several pieces of dry ice dropped in. I color the water in the graduated cylinder with food coloring. {bubbling columns demo} A plastic pumpkin also sits on my demonstration table next to a candle. You may also want to have some spooky music or noises playing quietly in the background and turn off some of the lights in your classroom. The basic premise of the story is as follows:
Conquered by a little light,
A flame will take away its might. The genie then gave him a map showing him how to find two special solutions which, when mixed together, would provide him with a big clue as to the answer of the riddle. He was also cautioned that he must burn the map after he finds the two solutions, but before he mixes them together. (Describe the map in some detail, and describe how the map details a wooded location very near the boys home, a place the boy was somewhat familiar with as he played there every once in a while.) He sets out to find the solutions. (This is where you need to adlib. I usually mention something about finding the second solution up in a tree, in the crook of a branch. You can also get detailed and mention the type of container the solutions are found in.) Upon having both solutions, he combines the two solutions but nothing happens! {halloween colors demo, only mix solutions B and C} He doesn't understand why nothing is happening. Then he notices that his hands are bleeding, he is running out of time! {bloody picture demo} He remembers that he was to burn the map before mixing the two solutions, so he rolls up the map, stands it up and lights it. {the mysteriously rising napkin demo} Next, he adds a bit more of the solutions to see what will happen. {halloween colors demo, add solution A to the already mixed B & C} He then sees the clue and is able to solve the riddle. The genie appears and grants him his wishes. Answer to the riddle...DARKNESS!

Note: for the Mysteriously Rising Napkin demo, use the thin sheets found in old mimeograph copies, it works best. You must also stand the "map" up to get the best effect. I have found that I need to pre-roll some "maps" before the class and use a glue stick to apply a VERY tiny spot that will keep the paper rolled. During the story telling I roll one up, set it aside, and then grab one of my pre-rolled "maps" to burn.
The only problem that has ever come up about the story is, how did the boy get matches to light the map if he never went home? He started smoking at a young age? It hasn't been that big of a deal yet.

At one of the subsequent ACTIVE Chemistry weekend meetings, in November, 1999, I was asked by one of the participants if I had come up with a similar type of thematic demo story for Christmas. Since I had not, this teacher decided to try to come up with her own story to use around Christmas. A copy of her thematic Christmas demo story is also included.
