Introduction – 3 minutes

Dry Ice Bubbles - 7 minutes

Materials Large bowl half filled with water Dawn dish soap (in a small bowl) Dry ice T-shirt or cloth strips Quarter

Procedure:1. Dry ice is unique because it isn’t like a water ice cube that melts into water,

but instead it goes from a solid straight into a gas. Because of that a quarter will “scream” when you put it on top.

2. Select a bucket or container that has a smooth rim and is smaller than 12 inches in diameter.

3. Cut a strip of cloth about 1 inch wide and 18 inches long (an old t-shirt works well). Soak the cloth in a solution of Dawn dish soap or use your favorite recipe for making bubble solution. Make sure that the cloth is completely soaked.

4. Fill the bucket half full with water. Have tongs or gloves ready to transfer the dry ice to the bucket.

Place two or three pieces of dry ice into the water so that a good amount of fog is being produced.

Remove the strip of cloth from the dish soap and carefully pull the strip across the rim. The goal is to create a soap film that covers the top. It also helps to have the rim wet before you start. This may take some practice until you get the technique mastered. Remember that a bubble's worst enemies are dirt, oil, and rough edges. Your patience will pay off in the long run.-

Black Jelly Bean Chromatography – 5 minutes to present (10 minutes required)

Materials: Small bowl of water Black jelly bean Filter paper Plate to set the filter paper on

Procedure:

1. Put a piece of filter paper so that it lays flat on the plate.2. Drop the black jellybean into a cup of water for about 5 seconds.3. Place the black jellybean in the center of the filter paper and allow it to sit

for about 10 minutes.4. While the jelly bean is sitting on the filter paper move onto surface tension.

Surface Tension and Soap (Drops on a Penny & Dancing Milk) – 7 minutes

Materials: Clean pennies Water Eye dropper Dish soap Whole milk Cake pans Food coloring Q-tip

Procedures:1. First, how many drops of water can fit on a penny? About 30 – why? Surface

tension2. Now, how many drops of water and soap will fit on a penny? Surface

tension decreases so only about 12 drops fit.3. Mik has fats in it that are attracted to each other, just like the are attracted

to your hands. These fats are kind of like dirt, so what happens when we add soap?

4. We overcome the attraction the fat molecules have and they separate5. Soap will also remove the dirt and oils from our hands when we wash them.

Gobstopper Colors - 5 minutes

Materials: Gobstoppers White Plate Pitcher of water

Procedure:1. Fill a petri dish with enough water to cover

the bottom.2. Drop a Gobstopper of a different color along

the edge of the petri dish. We would tell you to put them all in the corners, but the dish is round and doesn’t have corners. So you need to place the Gobstoppers at equal distances from from each other.

3. Now watch the colors.

Disappearing Marbles (7 minutes)

Materials: Water marbles (pre-soaked) Two medium glass bowls – one with water and marbles and another with

just marbles Large graduated cylinder “Happy Halloween” message

Procedure1. The night before the experiment put some of the jelly marbles in water to

soak.2. Start with a bowl of water and clear jelly marbles.3. Can you pull something out of the bowl? Ask for a student volunteer to put

their hand in the bowl.4. Show another bowl with the marbles in them. Show what happens when

you add marbles to water. Why? Refraction index makes the marbles seem to disappear because they are made mostly of water. (They grow approximately 300x their weight in water)

5. Show the secret message on the document camera by using a bowl of jelly marbles and adding water to it from a pitcher to reveal “Happy Halloween” – Use this as a conclusion

Oozing Pumpkins - 5 minutesMaterials:

Carved pumpkin Plastic cups Hydrogen peroxide Small graduated cylinder Dish soap Food coloring Yeast Warm water

Procedure: 1. Fill a small cup with 30 mL of hydrogen

peroxide (12%).2. Add a squirt of dish soap to your hydrogen peroxide.3. Mix in some some food coloring to give your reaction a bit of effect.4. Open up the top of your jack-o-lantern and carefully lower the cup of

mixture into the jack-o-lantern. Don't tip it over or you'll have to start over from the beginning.

5. Now you're going to need to create your Elephant's Toothpaste catalyst. Mix an entire package of dry yeast with 4 tablespoons of very warm water

in a small plastic cup. If the mixture is too thick, like a paste, add a little more warm water to thin it out.

6. Pour the yeast solution into the cup and quickly replace the top of your jack-o-lantern. It may take a few seconds, but once the reaction starts the result is well worth the wait.
