In this class we'll cover how to make this wonder of a … As you pump air into the bottle the pressure inside the bottle builds up until the force of the air pushing on the water is enough to force the cork out of the end of the bottle. In this article I’ll show you how to launch a bottle rocket adventure with your family. The rocket will shoot up quite fast and high so remove any obstructions and warn anyone around you before you launch it. Build a rocket launcher with your kids and every time you finish a 2-liter bottle of soda pop, you can send it soaring. 2-4 Bicycle Pump Air Rocket launching apparatus (parts and construction details follow) 2. Regular pumps can supply in the order of 100-120psi. Other than the rocket and launcher, you’ll need water as “fuel” and a bicycle pump. Step 11: Launch the Rocket. Put your rocket on the open end of the tubing, take aim and stomp on the bottle to launch your rocket. Make a launchpad that holds the bottle with the neck downwards, lets you attach the pump and stand behind the bottle. You won’t be able to estimate without one, and it’s important to avoid over-inflating your rocket. Let’s make this bottle look like a real rocket. Did you know you can make and launch a water bottle rocket using just a plastic bottle, water, cork, needle adaptor and pump?.
But, why have a boring rocket? The instructions that follow explain how to construct the launcher and provides a list of needed materials.
This project was originally inspired by the howtoons about bottle rockets. A soda bottle can easily withstand 150 pounds of pressure per square inch—significantly more than a car or bike tire, and more than enough to launch it into flight. air delivered by a hand bicycle pump or small compressor. Now you can attach a bike pump or air compressor to the tire valve. Attach a bicycle pump to the valve coming out of the tee. Pressurize the system to between 60 psi and 75 psi. Make a bottle rocket adapter just using recycled materials! To launch the rocket: Hold the rocket by the neck of the bottle and pump air into it. The cork is drilled out and attached to a bike tube valve and a length of vinyl tubing. The launcher's air hose connection will need to have a tyre valve adapter in order to connect the bicycle pump directly. This pressure will cause a cork to eject and then use the water as a propellant to blast off. To reuse your stomp rocket launcher, blow air into your bottle, using a bike pump or just yourself. The pressure is released in a split second through an electric sprinkler valve, sending the paper-and-tape rocket into the sky. The launcher is made from PVC pipe, and has a chamber that’s pressurized using a bicycle pump.
