A Smarties box gives you two treats in one. The chocolate candy is a treat, of course, and the box can be transformed into an annoying, and therefore fun, whistle. Milk Duds, Mike and Ike, and Good & Plenty are other candies packaged in a similar way. Before tossing these empty candy boxes in the recycle bin, reuse them by creating a band of mini instruments.

Tips and warnings

  • Larger candy boxes are more difficult to insert into your mouth but can be effective as whistles.
  • Do not open both ends of the candy box. Even if the ends are resealable, your whistle is less likely to perform and may burst open when blowing air through it.
  • If your mouth is too wet, the box will become too soggy to work effectively. Empty another box of candy and make another whistle.
