S tep 1: Building an Airplane
This operation is to make the air plane using the aluminum.
M aterials:
Two aluminum canes Glue Scissors
Gloves M etal ruler
M ethod:
Cut the upper part of the canes and join the two canes with glue to make the body
of the airplane.
- Cut the upper part of the cans.
- J oin the cans.

S tep 2: Filling the H elium gas.
The H elium gas is lighter than the atmosphere air. So it will help the balloon to float
in the air. At the same time it also will carry the airplane.
M aterials:
Balloon (Gred G-20) 100 l of H elium gas Valve (40 gm)
M ethod:
Fill the balloon with approximately 100 l of H elium gas. Tight up the valve at the
mouth of the balloon to control the amount of H elium gas. Connect the balloon with
the airplane using thread.
- H old the balloon carefully during filling
the H elium gas.
- Carefully tight up the valve.
- Connect the balloon with the airplane.

S tep 3: Connection with Balloon and the Support.
Tight the airplane with nylon thread.
Connect the air borne vehicle with the support to hold the air borne vehicles
position in the air.
M aterials:
N ylon thread Scissors M etal stand
- Tied with nylon thread.
- Tied with metal stand.

S tep 4: Preparation of Air Chamber
Fill the balloon with the atmosphere air. M aterials:
Insert the balloon into the air chamber. M odel of air chamber Balloon
Pump
M ethod:
H old the balloon carefully and fill it with atmosphere air.
S lowly insert the end of the balloon into the air chamber without tight up the mouth
of the balloon.
H old the mouth of the balloon for the next step.
- Fill the balloon with atmosphere air.- Insert the balloon into the air
chamber.

Hold the balloon gently and release the atmosphere air and observes.
M aterials:
Bull eye
M ethod:
H old the mouth of the balloon and observe the position of airborne vehicles.
Gently release the atmosphere gas and observe the movement of the vehicle.
- Release the atmosphere air.
- O bserve the position of the air
borne vehicle.

SAFETY MEASURES AND PRECAUTIONS
We have to implement many safety measures in completing the experiments
to minimize any untoward incidents and also to avoid contamination of the
experiment area. This is important to obtain better model of an air borne
vehicle and improve our results. Some of the measures include:
Very careful in handling apparatus like the scissors and aluminum cans to
avoid injuries to fingers.
Wore gloves when handling the aluminum cans. Wear goggles during the experiment to avoid any substance or materials from
entering the eyes.
Always guided by elders during the experiment.
