Bottle Rocketry

Want to launch your own rocket and see how far it flies?

A Rocket is a vehicle that uses jet propulsion to move forward.

The principle of rocket propulsion works on Newton’s Third Law of Motion. It states that ‘for every action, there is an equal and opposite reaction’. As far as the rocket is concerned, the engine of the rocket releases hot burning fuel in the downward direction.

Uses of Rockets:
– Rockets are used for launching satellites into space.
-Rockets are used to transport humans and spacecraft into space.
-Rockets are used for military applications.
-Rockets are used for space explorations.

Now that we know about rockets, let’s make our own bottle rocket!

Got a kit in your hand? let’s see what it consists of:

  • Foam sheet
  • Empty bottle
  • Bottle cork
  • Paper glass
  • Citric acid
  • Baking soda

Steps to be followed for making your own Bottle rocket:

Step 1: Fix the launch pad, as shown in the figure.

Step 2: Set the bottle cork in its slot, as shown in the figure.

Step 3: Cut four pieces of fins to be added to the bottle from the given foam sheet, as shown in the figure.

Step 4: Stick the fins on all the 4 sides of the bottle, as shown in the figure.

Step 5: Mix three spoons of citric acid crystal and baking soda, each equal amount, as shown in the figure.

Step 6: Fill 1/3rd of water in the bottle as shown in the figure.

Experimenting with our bottle rocket!

  • Take the bottle that was filled with 1/3rd of water.
  • Add the mixture of citric acid and baking soda to the bottle.
  • Fix it to the launch pad mounted with the bottle cork.
  • Tilt the bottle and wait for the reaction to happen.
  • The bottle rocket will be launched by itself due to the chemical reaction.

Now that you have built your own bottle rocket,

  • Launch and clock the duration of how long the rocket remains in the air.
  • Launch and check how far your rocket goes.
  • Try launching it with a lesser quantity of the mixture of baking soda and citric acid mixture and see the difference.
