I came across the website Instructables.com a little while back. What it is, is it do it your self projects, in many different categories. You can sign up and make your own how to or work with others. It is a really cool idea. I found a really good one. It is how to make a smoke bomb out of ping pong balls. I think it would be cool to try. If it would it would be great for paintball games. It is small enough to fit in your pocket. You can check out that how to here.
