 【Reminder】
(1) Due to the lack of contractility of aluminum foil balloons, it is essential to inflate them slowly. You can use an air pump to inflate them to 90%, and then blow them with a straw to facilitate controlling the amount of air, to avoid bursting. If there is a situation where two layers of aluminum foil are stuck together, you must stop inflating and gently pull the two layers of aluminum foil apart before continuing to inflate, or it is easy to damage them.
(2) Sharp objects, dirty ground, direct sunlight, and excessive compression can easily cause damage or rupture to the spheres.
(3) Due to the thermal expansion and contraction of gases, in winter or when the temperature drops, it is necessary to appropriately inflate aluminum film balloons; in summer or when the temperature rises, it is necessary to release the air appropriately to avoid bursting. Generally, after being inflated with helium or hydrogen, they can float for 6-14 hours, so helium or hydrogen must be filled on the day of use (when filling hydrogen, safety must be carefully noted).
(4) Aluminum foil balloons have no stretch, so please do not inflate them too much. Due to the thermal expansion and contraction of gas, when summer or the temperature rises, it is necessary to release air from the aluminum foil balloons to prevent them from bursting; in winter or when the temperature drops, it is appropriate to inflate the aluminum foil balloons. Do not use an electric air pump to inflate, but use a manual air pump.
(5) If it is accidentally damaged during use, you can immediately use transparent tape to paste it and add gas, and then you can use it with confidence.
