Next time you're outside, pluck a blade of grass for an easy way to entertain yourself – and annoy your friends.
Next time you're outside, pluck a blade of grass for an easy way to entertain yourself – and annoy your friends.

Pick a flat blade of grass that’s as long as your thumbs.
You’ll get more sound from wide, slightly coarse grass than from thin, fine grass.
Press your thumbs together at the knuckles with your fingernails facing you. Put the grass lengthwise between your thumbs.
Pull the grass taut, so there are no kinks. You should see the edge of the blade centered in a gap between the base of your thumbs and your knuckles.
Purse your lips, put your mouth to your thumbs, and blow. You may have to move your lips or thumbs slightly to make a sound, so keep trying.
By cupping your hands, you can make the pitch of your whistle higher or lower.
Play around with different kinds of grasses and reeds. You can make as many different sounds as there are blades of grass on your lawn.
A grass whistle isn’t technically a whistle; it’s a reed instrument.
