Assemble the catapult arm: Join 2 pencils together perpendicularly to make an inverted lowercase t secure them with rubber bands.Punch a third hole on the opposite short side it should be centered and near the bottom. The holes should be large enough for a pencil to rotate easily. Punch a hole in a long side of the box, 3 inches from a short side.Play around with the position of the stopper to get the maximum angle and distance for your launch-and have fun with colors and decorations.

This simple machine uses stored energy (the tension in the rubber bands) to release a projectile (called the payload). Note: If after some use, one of the straws cracks, simply replace it with a new one. Bend the flexible straw to aim and place the rocket straw over the end.

To launch the rocket, inflate the pouch by blowing into the flexible straw.

Add this to the top to seal the straw completely. Add washi tape to decorate the straw if desired.

Tape one half-fin perpendicularly to each full fin as shown.Tape the full fins on each side of the straw.Make three trapezoids from cardstock, in the following dimensions: 3 inches (base) x 1 inch (height) x 3/4 inches (top).Insert the pointed end of the straw into the straw hole of the juice pouch.Snip off the end of the flexible straw on an angle.One flexible straw (that comes with the pouch).(Budding engineers take note: This is called pneumatics!) This rocket from Ana Dziengel of Babble Dabble Doo uses the power of compressed air to launch into the sky.
