If you've ever wanted to chirr like a cicada or buzz like a bee, just take this humming noisemaker for a spin. When you swing it around by its string, the passing air causes the rubber band to vibrate, resulting in a droning insect sound.
To make one, start by slipping a pencil eraser onto each end of a craft stick.
Trim an index card into a 3-inch square. (We decorated ours with wasplike stripes.) Center the card between the erasers and staple it to the craft stick.
Tie one end of a yard of string on the craft stick between the card and eraser. Stretch a flat rubber band around the eraser ends, as shown. Get your hummer buzzing by swinging it in a circle above your head.
