Nice video! I think the most interesting part is why the large matches take longer to ignite. It makes you wonder what would happen if a match stick were made of Al instead of wood. Could it be lit?

Great way to demonstrate activation energy. Sweet and simple

You are probably right. I was just going by what I thought it was. I probably should have looked it up first. Thanks Hayden :)

Are you sure that it is red phosphorus at the end of those matches? I know it used to be used, and I could be totally wrong, but ive read from a few sources that it is potassium chlorate/red dye at the end of the matches and glass/red phosphorus on the strike pad.
