Jumping Bird/Cup rocket

Step-1: Prepare some decorative stuff for your Rocket

Construct wings, a rocket or what you think is suitable out of construction paper to decorate the rocket with

Step-2: Preparing Rocket

We need a strong rocket, so I am going to layer it up with another cup.

Just cut the edge of the cup and insert it in another cup to make two layers.

Take a paper cup and put two holes by inserting a needle one point of the cups side to the opposite side of the cup. Such that the two holes remain quite opposite to each other.

Make sure you are keeping these holes near the brim of the paper cup mouth area. Repeat the same process of making hole on the other side of the cup. That means you are making four holes on the four sides of the paper cup.

Step-3: Inserting Bands

Pick two rubber bands and cut them at one point. Then, insert the line of rubber band into any two holes in opposite sides of the cup and tie its end part to keep a knot on both ends. Such that the inserted band will not slip out of the holes.

Repeat the same with the other line of band and keep tight knots into the other set of holes around the cup. Finally, after tying bands to the holes of the cup, you can see plus shape at the open side of paper cup mouth brim.

Step-4: Glue the Decorative Stuff

It is time to decorate our rocket launcher! Keep the paper cup which is referring to the rocket part, upside down.

Step-6: Flying Paper Cup Rocket

In this step, pick another paper cup and place it in reverse position such that the paper cup is in upside position. We are going to use this inverse paper cup as a base part or launcher for your space rocket.

Now place your rocket on top of the base cup but in upside down position. Make sure the base is also in inverse position. Then, give a gentle pressure just with the bear hands and push the rocket towards the base. After pushing it over the base part, release the pressure on the rocket part.

Science behind How Paper Cup Rocket Fly

What Newton’s Third Law of Motion says? It says; “every action has an equal and opposite reaction”. Satisfying the newton’s third law, the rocket part when you push downwards over the base part and release, it flies into the air. That means the amount of pressure you give on the rocket makes it fly with the same amount of energy and force upwards after releasing the pressure.
