Carefully review the general safety advice on the back of the box cover before starting the experiment.
Keep flammable materials and hair away from the setup.
Keep a bowl of water nearby when working with fire.
Do not leave the candle lit after finishing the experiment; this is a fire hazard.
Create a special muzzle for the vortex cannon!
The elastic wall of the balloon pushes the air projectiles out of the cannon.
The target will be a burning candle! Load the cannon and pull the trigger. Did you hit the target?
Dispose of solid waste together with household garbage.
The propeller continuously pushes the air and creates a stream . In the cannon, the air is pushed out by the release of the latex membrane. As a result, a rapid airflow forms inside the tube directed towards the outlet. Since the hole is narrower than the tube itself, the airflow is forced to accelerate as it passes through.
Escaping from the tube , the central airflow only collides with the stationary air located in front of the exit. The surrounding airflow interacts both with the walls inside the tube, and with the outside air. Therefore, the surrounding airflow moves more slowly than its center.
The surrounding airflow is simultaneously held back by the stationary air and pushed by the rapid central airflow. As a result, the airflow begins to roll up like a scroll . It forms the shape of a donut that flies forward. The outside air gently slows down the air donut , which itself consists of spinning air. In other words, the air donut gently shifts the outside air from its path, without colliding with it. Such a donut retains its speed longer and can travel a far greater distance than direct airflow .

Kids are now able to engage with science in a way that they simply wouldn’t have been able to in the past as they shrink themselves down to see the world at a molecular level
