Relaxing by the sea can be even more fun and exciting when you find the right activity on the beach. Especially if you are resting with children who have already gotten fed up with mosaics made of stones and shells and even fabulous fortresses made of sand. Please them and yourself with a new entertainment - a boat with a water engine. You can find materials for it on the beach.
It is necessary
- Plastic bottle with screw cap
- A piece of styrofoam or wood
- Cocktail tube
- Bicycle Pump
- Round pharmaceutical rubber bands
Instructions
Step 1
Take a piece of foam or wood and cut a boat out of it. Calculate so that the boat's hull can hold a bottle filled with water. Cut out a few more pieces of Styrofoam that you will need to lift the bottom of the boat.
Step 2
Make a hole in the bottle cap and insert the cocktail tube into it. Make a small hole in the bottom of the bottle and plug it with a cork. The best way to pierce the hole is with a 1 mm nail. Cut a small plug out of the foam and plug the hole.
Step 3
Open the bottle cap and fill the bottle with water. You need to collect a full bottle. Screw on the stopper. Place the bottle on the boat so that the stern tube goes into the water and the bottle is tilted upside down. The hole with the foam plug should be at the very top of the structure. You can lift the bottom of the bottle by placing several pieces of Styrofoam under it and connecting them to the bottle and the boat hull with ordinary rubber bands.
Step 4
Submerge the entire structure in water and open the foam plug. The boat will float and keep moving until the water runs out..
