here is how to make a pen cannon with more power than a normal one. i used two springs. i will add another instructable with more indepth construction and better photos
You probably should have waited until you built the object before creating the 'ible. This would have been better suited as a forum topic.
i have built it just didn't have it with me when i made picture and made pic in a hurry
Instructables aren't supposed to be "hurried". They're supposed to feature detailed step by step instructions. Slow down, and create a quality product.
very good point. i am currently working on making a modified version of this using different pens and springs to see which works best. i will make a very detailed instructable.
