Things You'll Need
Instructions
Inflate a long tube balloon. Count to three as you let some air out of the balloon and tie the end. The balloon needs to be a little deflated so you can make the twists without breaking it.
Measure about 10 inches from the end and make one twist to section it off. Measure 2 inches down from the first twist and twist again to make a 2-inch bubble. Twist the two twists together clockwise on either side of the bubble to make a "pinch twist" that locks the twists in place.
Measure another 10 inches down the balloon and twist off another 2-inch bubble. Twist the two twists together counterclockwise, so that the balloon is in a zigzag shape.
Fold the zigzag balloon so that the two 10-inch sections are below the longer section. Grab the middle of all three sections together and twist them together.
Arrange the balloon into a 5-inch-long upper section of the cross, with two double sections as the arms of the cross and the longest end pointing downward.
