We decided to use Bottlerocket for several reasons : We use Bottlerocket as the base OS for all the nodes of our Kubernetes clusters which run hundreds of microservices on top of them. PedidosYa engineering platform is based on a microservices architecture running on containers. The action force created by the water and air being expelled downwards out of the bottle causes the reaction of the bottle being pushed upwards.PedidosYa, a brand of the German multinational company Delivery Hero, is a leading online delivery company in Latin America that connects millions of people with thousands of restaurants, markets, pharmacies and other partners in 15 countries. The third law states that for every action, there is an equal and opposite reaction.This causes the rocket to accelerate upwards faster. Adding a little more water increases the mass of the rocket, which then increases the action force applied as the water is expelled by The amount of force pushing the rocket upwards depends on the volume of air pumped into the rocket. The second law illustrates the relationship between force, acceleration and mass.In this case, the bottle rocket remains at rest on the launch pad until the force from the bicycle pump acts upon it. The first law states that an object will remain at rest unless an unbalanced force acts upon it.The motion of the bottle rocket illustrates Newton’s three laws of motion: Make observations and record your data.Once the cork can no longer withstand the buildup of pressure inside the bottle rocket, it will pop out and the rocket will be propelled into the air! Safety First! Once you start pumping, do not approach the rocket. Stand as far from the rocket as you can while you pump air into the bottle using the bicycle pump.Add duct tape if needed to create a tighter seal. Reinsert the plug into the bottle rocket and make sure there is a tight seal around the nozzle so that no water leaks out.Add water to your bottle rocket until it is about 40% full.Place the blocks side by side on the ground, leaving a 3-4 cm gap between them where the bottle nozzle will sit. Use your foam blocks, wooden blocks or bricks to create a launch pad for your rocket.Attach the cone nose to the bottom of the bottle, which is the top of your rocket.Cut a piece of thin cardboard or card stock and tape it into a cone to act as the nose of the bottle rocket.The top of the bottle will act as the bottom of your rocket, so position the flat edges of your fins downward to support the bottle when it stands upside down. Tape the fins to the flat part of the bottle closest to the nozzle.Cover the fins in duct tape to help minimize water damage.Cut a piece of thick cardboard into three or four triangles of equal size to create fins for your rocket, or use a different shape for your fins.Leaving the pump needle in place, remove the plug from the bottle and attach the needle to the bicycle pump hose.If it does, try adding some duct tape to the plug to create a tighter seal. No water should leak from the plug or the pump needle. To test this, add some water to the bottle, reseal it with the plug (with the needle still in place) and flip the bottle upside down. Push your pump needle through the hole until it is secure.

If you do not have a drill with a drill bit the same size as your pump needle, create the hole using pliers and a nail instead.

With adult assistance, drill a hole through the centre of the plug.

Safety first! Put on protective gloves and safety glasses before moving on to the next step.

Once you’re done, remove the plug from the bottle. Alternatively, line your existing plug with duct tape to make it larger. If it isn’t a snug fit, find another material to use as a plug.

Insert your cork or rubber stopper (the plug) into the top of your plastic bottle to make sure it’s a tight fit.

You’ll need a flat, open area with nothing overhead.

Find an outdoor space with lots of room to complete this activity.
