*SIMPLE ROCKET*


Physics isn’t difficult subject or isn’t scary thing for students. It’s FUN, we can make toys using physics concepts. yupz,., Using the concept of air pressure, we can create a Simple-Rocket from unused object.

 When the rocket pumped by the water, in the rocket get the pressure of the pump. The Air is pumped into the bottle make the bottle harder. It means that the air has a pressure. The more we pumped air into the bottle, the greater the pressure received by the bottle, otherwise the less air pressure less well received. When the bottle cap can’t hold the pressure of the air inside the rocket, so the rocket will be pushed from the bottom of the rocket.
