Helicopter || How to make helicopter with use bottle || school project || science project


Making a simple helicopter using a plastic bottle can be a fun and educational project. Here's a basic guide on how to do it:

Materials Needed
A plastic bottle (preferably a small one)
A pair of scissors or a craft knife
A small motor (like those used in small toys)
Propeller (you can use a ready-made one or make one from a plastic bottle)
A battery holder with batteries
Wires
Tape or glue
A small switch (optional)

Steps

1. **Prepare the Bottle**:
Clean the plastic bottle and remove any labels.
Cut the bottle in half horizontally. The bottom half will be used for the helicopter's body.

2. **Make the Propeller**:
If you don't have a ready-made propeller, you can make one from the top half of the bottle. Cut out two or three blades from the plastic and attach them to a small circular piece of plastic. Ensure they are balanced for smooth rotation.

3. **Attach the Motor**:
Secure the small motor to the cap of the bottle. You can use tape or glue to ensure it's firmly in place.
Attach the propeller to the motor's shaft.

4. **Connect the Battery and Switch**:
Connect the wires from the battery holder to the motor. If you're using a switch, connect it in between the motor and the battery holder.
Secure the battery holder inside the bottom half of the bottle using tape or glue.

5. **Assemble the Helicopter**:
Place the top half of the bottle with the motor and propeller onto the bottom half of the bottle, ensuring everything fits snugly.
Use tape or glue to secure the top half to the bottom half.

6. **Test the Helicopter**:
Turn on the switch (if used) or connect the batteries to start the motor. The propeller should spin and, if balanced correctly, create lift.

Safety Tips
Be careful when using scissors or a craft knife.
Ensure the motor and propeller are securely attached to avoid any accidents.
Supervise children if they are making this project.

This simple model won't fly like a real helicopter, but it will give you a basic understanding of how a helicopter's lift mechanism works.
