How to make a boat out of plastic bottles, how to make a boat out of bottles

Homemade electric boats.

1. Equipment. Toy motor, No. 5 battery box (containing 2 No. 5 batteries), plastic propeller, waste ballpoint pen refill, styrofoam block, screw nut, waste plastic bottle, multi-strand wire.

2. Production. The bottom part of the plastic bottle is used to design and make a bracket for the motor and battery box. The shaft of the motor is pierced through the small hole at the bottom of the bottle, and then fixed with plastic sheets and screws.

Insert a ballpoint pen refill with a copper tip at one end into the motor shaft. The battery box is fixed with screws in the bracket, the motor is connected with a wire, and the battery is installed, and the motor can rotate.

Design and make a hull with styrofoam blocks, and hollow out part of the hull according to the size of the bracket and the installation position.

Install the bracket to the hull to remove the styrofoam, let the ballpoint pen refill installed on the motor shaft penetrate through the hole in the tail of the hull, adjust the position of the shaft so that it can rotate freely, fix the bracket, and then install the propeller. The hull can be decorated.

3. Experiments. Assemble the boat and put it in the water for smooth sailing. If you can't sail normally, you need to debug according to the existing problems (Problem:

1 What should I do if I turn on the power and put the boat into the water, but the boat moves backwards? Change the position of the positive and negative terminals of the battery, change the direction of rotation of the toy motor, and the boat will move forward. 2 How to add a rudder to a small boat to control the direction of sailing. ）

How to make a boat out of a bottle is as follows:

1. First of all, prepare a plastic bottle in good condition, and the original lid should not be screwed off, just screw it on it normally. Then prepare a knife, a sharp knife is best, it will be sharp.

The boat is made as follows:

The materials we need to prepare are: a rectangular piece of paper.

1. First fold in half along the middle.

2. Fold it in half again to the middle.

3. Fold both sides in half to the middle.

4. Fold the bottom edge upwards respectively.

5. Stretch out from the middle.

6. The corners of the bottom edge are folded upwards respectively.

7. Stretch the middle open.
