First, we must have a big basket of PVC pipe of all shapes and sizes. These are essential for sticking a little arm through to play robot or to use as knight armor.
Next up, old pots and pans. Especially important are the lids. Those are shields, of course. But the pots are also important for drumming, hiding stuff in, and the pans are handy for hitting your brother. Ooops. Blowing that 'perfect home school family image' again!
This is the tube off my husbands shop vac. Well, not the actual one, but one like it. They need their own so they can play elephant. Also just for plain coming up behind someone and yelling really loud in their ear without getting too close. That's loads of fun! Also, if a little boy wraps it around his shoulder it can be an ammo belt. I have no idea if there are any ammo belts worn around the shoulder, but by the way they swagger it has the look and feel of a real one!
These look like measuring spoons, don't they? Wrong! They are actually keys. And the boy that swipes these from my kitchen drawer and loops them into his belt has all the swagger and authority as the guy who has the keys to the elevator and the executive bathroom. Instant status.
Tongs are very important if you might like to play pirate. They are a step up from a hook if you have happened to have had your hand chopped off in a sword fight.
Yarn. To tie to every conceivable object in sight and drive your mother a little batty. I have to admit I'm a little reluctant on the yarn. But this is self defense, you see. I'm trying to protect my own stash.
And lastly, hair ties. For shooting at people. (Well, I figure they sting a little less than rubber bands.) And fastening little objects to your belt loops-like if you need even more keys.
