My name is Harlow, and I have been doing science fair for 4 years. I am a competitive all-star cheerleader and love working with people. My top career choice would be to teach science to younger people so they can share the experience I have had. I first became intrigued around the topic of chemistry earlier last year as I was fascinated by the elements of the periodic table. I was in the middle of trying to find an interesting topic and I found a video online about how to make edible “balloons”. I dug deeper and tried to figure out how it worked, specifically, why the “balloons” did not deflate within minutes. It was that day that I decided to set off on this discovery of the porosity levels of different solutions and the rate at which helium escapes solutions. For further investigation, I plan on using different gases, and sugar-based liquids to add to my experiment. If I were to give any advice to a newcomer to the science world it would be: investigate what intrigues you and to keep asking questions, like all good scientists do. And even when people tell you to give up keep going.

The Rates that Helium Escapes Through the Porosity of Different Solutions
Region:Northwestern Ontario
City:Thunder Bay, ON
School:Bishop Gallagher
Abstract:The purpose of my experiment was to test the rate that helium escapes through three different solutions/”balloons” that are of various porosities. This experiment is interesting because it is a demonstration that shows helium particles escaping from a solution. It is important to understand porosity so that we know how to safely contain dangerous/life-saving chemicals/gases such as oxygen/chlorine without fail will save many lives.
