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.
