1. First prepare the balloon to be inflated, as shown in the figure.

2. Before inflating the balloon, the inflator should be turned on and off, as shown in the figure below. Press and hold the switch, and the power indicator will light up.

3. The inflation nozzle of each balloon has an indicator color, as shown in the blue part of the figure below.

4. Pull out the blue leather and put it into the air nozzle of the air pump.

5. Press the inflation nozzle downward to inflate the balloon.

6, balloon in the process of inflation should always pay attention to the inflation state.

7. Finally, just fill the balloon with air, as shown in the figure.

Matters needing attention in the use of hydrogen balloons:

When hydrogen rubs against other objects to generate static electricity, flammable and explosive hydrogen will burn and explode when it encounters open flame, high temperature and electric spark.

Hydrogen balloon, a lightweight bag-like or saccular object, is filled with hydrogen and is the lightest, with a density of 0.0899 grams per liter. An object that can float upward by the buoyancy of hydrogen is called a hydrogen balloon.

Hydrogen balloons generally include rubber hydrogen balloons, plastic film hydrogen balloons and cloth-coated hydrogen balloons. Smaller hydrogen balloons are currently used for children's toys or holiday flights.

Larger hydrogen balloons are used to hang advertising banners, also called floating hydrogen balloons. In meteorology, hydrogen balloons are used to detect high altitude. In the military, hydrogen balloons are used to set up communication antennas or distribute leaflets. The internal frequency of the hydrogen balloon is close to 20Hz.
