Things You'll Need:
- Piece of construction paper (color not specific) Large pack of normal tear-shaped balloons. Pair of scissors Tweezers Tape
-
Step 1
Take a balloon and look at the spout of the balloon. The hard part about balloons when they take off is that they are a constantly changing mass that has unchecked propulsion and movement. Their shape is constantly changing, likewise making the spout constantly change position, giving them that erratic flight path.
-
Step 2
Cut a strip of construction paper that is ½ inch wide and 3 inches long. Roll it up into a tube. Make it as tight as possible. Insert it into the spout of the balloon and let it unroll. When it completely fills the hole, grasp the center of the spiral and pull it down into a cone.
-
Step 3
Tape the cone completely. Use as much tape as it will need to make the cone one solid piece of tape and paper. Leave a hole in the bottom of the tube.
-
Step 4
Roll the lip of the balloon's spout off the top of the now solid cone and blow the balloon up. When it is full, pinch the balloon higher up, leaving most of the spout exposed. Roll the lip of the spout onto the cone.
-
Step 5
Let go of the full balloon with spout inserted. The balloon will still change shape but will only deviate slightly from its upward trajectory.
