DIY your own foam battle gear for your little ninja

I have discovered that foam is an awesome replacement for what could potentially be a dangerous object. It's malleable, flexible, strong, lightweight, and unless you take it directly to the eye (which could happen with any toy), it's pretty darn safe. I like to use either thin pool noodles, which are readily available at most discount chains during the late spring and summer, or pipe insulation foam, which is found year round at the hardware store; it comes in a variety of thicknesses so you can choose the one that suits you best.
