Fog Machine Experiment

Introduction:

Making a fog machine is simple and easy to do. Making a fog machine is good for: Parties, Halloween. When making it you need to be careful of how much and how little you put into your solution to make the fog.

When I did my research I found out there are many easy ways to do this experiment. You can use dry ice, or as I used, you can use glycerin liquid and distilled water.

Investigative question:

Will the solution of the glycerin liquid and distilled water work in the making of the fog? Hypothesis:

Depending on how much of each ingredient and how much warmth and spacing between the objects, the fog machine will work very well and produce a lot of fog.

Variables

Independent variable: Timing

Dependent variable:
Heat// temperature

Controlled variable: amount of solution used

Method:

1. Mix your solution:
The first thing you need to do is create a liquid mixture that will later turn into fog.
You will need to do things for this – distilled water and a liquid called glycerin. This chemical is normally is used to make soap as, when mixed in the right way, it’s a good moisturizer. Mix one part glycerin with three parts distilled water. When this solution is heated to a boiling point, it creates a dense vapour, and when this reaches room temperature air it turns cloudy.

2. Create a cone
Take a small aluminum pie case and a two-litre drinks bottle. Cut the top off the bottle to create a basic cone shape. This shape should fit perfectly over one small pie tin – attach it with masking tape to ensure it stays fixed on. Next get an empty soup can and poke several holes in it. Place a candle in the can shortly to heat the glycerin solution, and the candle needs a constant air supply to keep the flame burning.

3. Get Foggy:
You only need a teaspoon of the glycerin solution to fill a normal sized room with fog. Spoon the mixture into the fog machine through the top of the bottle-cone. Light a candle and put inside the soup can. Place the pie tin on top and when the glycerin solution heats up, the fog should start to pour out of the top cone. For more fog you can take a teaspoon and more
solution. Data:

Conclusion and discussion:

The hotter the boiling point is the quicker the solution turns into fog. I proved that if you add more solution to your pie can the more fog you get. My investigative question got a positive answer, there was eventually fog, I realized the first time that candles were to faraway from the pie tin so it didn’t heat up as quickly. But when I got bigger candles therefore making the heat hotter and moving the tin closer to the heat the solution heated up faster and made MORE fog than what there was before. The hypothesis was proved correctly, and there was a lot of fog that came out of the ‘’machine’ after I corrected my mistake as mentioned above. How could I improve the experiment? Next time I could use a different cone for the fog to come out because my cone- being made from a plastic bottle eventually melted. The next step would be trying to find a different and stronger solution that will create more fog. The sources of error was definitely the plastic cone which in the middle of the experiment started melting. In conclusion I figured out the science is all in the mixture, as mixture boils it gives off hot vapour that combines with the cooler air and then creates fog. Relevance:

It is mainly used when throwing parties, but is not relevant to life situations and crisis’s.
