Hello from Hero Dad*, i'd like to give you some simple tips on how to throw a rockin' Nerf gun birthday party. Essentially you just need to transform your backyard into a Nerf battlefield and the kids will do the rest. This is a sure fire way to have tons of fun at your next birthday party (ideal age is 6 to 12) for not much money (although there is a bit of work involved) using some easy to build Nerf games and Nerf battle modular forts.
*Hero Dad defined: any dad trying to impress his kids with some type of act or service
Lots of card board boxes (the bigger the better) I used 48x24x24
sharp razor blade or box knife
spray paint for camo
Step 1: Building Nerf Shooting Forts
If your backyard is like mine, then it probably not that conducive to a Nerf battle environment. So as a Hero Dad it was my job to transform the backyard so that is has mass appeal for an awesome Nerf war. There are several ways you can accomplish this task by using some large cardboard boxes. For the 1st barrier I just build a box (48x24x24) then cut it in half diagonally leaving one side in tact so that the box can fold out. I cut slots in each facing side for sniping action.
