There might be something more gratifying than making a little child laugh really hard but we don't know what that might be. This is really simple. Take some paper, make an airplane (or several) & do what comes naturally. You won't get them to go as high as the ones in the photograph (probably) but if there's a bit of breeze, you never know. (See here to review the physics of flight & good for you. Just don't be a nag about it. This is for fun.) ciao-meow/GGCM
