Let your baby learn physics by making water rockets

If you are too bored with traditional toys and feel useless when playing online games, try making and using rockets out of plastic bottles. Guaranteed this toy will be extremely interesting and help kill time quickly. With just a few items, you can create your own toy. Start doing it now!

Rocket 1 plastic bottle

Prepare

• 1 sheet of paper 20×28 cm
• 1 plastic bottle (1.5l bottle)
• Rocket Wing Materials (Thick cardboard or thin cardboard)
• Tape
• Drag
• Play Doh . Clay
• Glue (optional)

Materials for making launchers

Perform:

Step 1: Make a fire arrow

Use 1 sheet of hard paper to roll into a pyramid. To make the rocket beautiful and colorful, you can choose colored paper and decorate it as you like. Use tape to wrap around the fire arrow so that it is tight and even. The tape will make the fire arrow strong and waterproof (can use colored tape if desired).

Step 2: Make the rocket body

Use 1 big plastic bottle (1.5l water bottle) to make the rocket body. If you want more color and beauty, you can use paint to decorate. Continue to take the fire arrow and attach it to the rocket body with glue or tape, try to align it so that it is straight and the 2 parts stick together, not loose.

Step 3: Make rocket wings

Use a thin piece of cardboard cut into 3-4 triangles to make the rocket’s wings, try to cut the right angles so that they can keep the rocket upright. You should use hard and waterproof paper to do.

Attach the wings to the lower part of the rocket. Bend the sides of the triangle to make it easier to attach to the rocket body, then glue or tape on it. Mount the bottom edge of the wing in line with the bottom of the rocket’s fuselage to help keep the rocket steady

Step 4: Increase rocket weight

You use a heavy object such as clay or clay to increase the weight of the rocket, so that the rocket can jump when launched.

Attach modeling clay or clay to the ridges on the top of the bottle to form a rounded tip, then use tape on the outside to secure.

Step 5: Pour water into the bottle

For the rocket to fly and fly far, you pour water about 1/3 of the body of the bottle.

Step 6: Make a flying head

Use a corkscrew and poke a small hole through the cork. The hole is about the size of the valve head of a bicycle pump, then, insert the stopper into the mouth of the bottle.

Next, insert the bicycle pump needle valve into the opening on the cork so that the valve fits snugly into the cork.

Step 7: Launch the rocket

Place the rocket vertically, hold the rocket at the neck of the bottle and point it away from the face.

Pumping air into the bottle, the rocket will launch when the cork can no longer withstand the air pressure in the bottle.

Release your hand for the rocket to launch.

Note: Please do it in a spacious and empty place. The rocket will go pretty fast and high, so you need to remove all obstacles and warn everyone around before launching the rocket. In addition, when the rocket launches, water will splash so you may get wet. In particular, you must not get close to the rocket when the pump has started, because it may cause injury.

Above is how to make rocket toys. Please refer to and pay attention to the notes to ensure safety when playing. Good luck!
