What you need: Nine 11″ balloons (to make 3 balls), funnel, scissors, 2-1/4 cups of dried lentils

Step 1: Stretch the first balloon by inflating it halfway, holding it closed for about 30 seconds, and deflating it.

Step 2: Place a funnel in the balloon’s neck and gradually pour in 3/4 cup of lentils, pushing them in as you go. The balloon should be firm but squeezable.

Step 3: Snip off the balloon’s thick rubber lip. Cut the neck off a second balloon and gently stretch the opening.

Step 4: Ease the second balloon over the filled balloon, tucking in the neck as you go.

Step 5: Cut the neck off a third balloon, stretch the opening, and ease it over the other two.

Repeat this process to make a set of three balls or as many as you like.
