Science Buddies: "Ask an Expert"

I'm currently working on the 'Getting a Bang out of Breath Spray' experiment. I conducted it today and I'm trying to come up with a purpose of theory question. I don't know what to put because I don't know what the purpose of it is supposed to be!! Please someone help!!

This is my current statement of purpose:

What is the most efficient technique of launching a canister filled with trapped ethanol?

Hi,
I think you have the right idea of what the purpose of your experiment is. Sometimes it helps to reread the summary page of the experiment to review what the project is about.

Hope that helps
