Chain Reaction Contraption

I am creating a contraption that, when you drop a ball down it, it will create a chain reaction leading to a goal like opening a can of soda. I love to build things and I thought that this might be a project that I will enjoy. More information will follow on future posts on this blog.

(Edit 10/26/10) I decided that I want to somehow include a motor in my contraption. I have an idea of how I can use it but I am still working on it. Soon I am going to start drawing my rough draft.I am open to suggestions so please comment if you have any ideas. Thanks!

(Edit 12/15/10)I just finished my rough draft today. I am going to make a final draft (that’s lest confusing.) I will make sure with my dad that it won’t be a lot of money and I will start building it as soon as I can!
