[Tips]]
(1) since the aluminum foil balloon has no contractility, it must be slow when inflating the aluminum foil balloon. It can be filled with tire pump to 90%, and then blown with a straw, which is convenient to control the gas volume to avoid bursting. If there are two layers of aluminum film sticking, be sure to stop inflating, gently pull the two layers of aluminum foil by hand and then inflate, otherwise it will be easily damaged.
(2) sharp objects, unclean ground, direct sunlight and excessive squeezing are easy to damage and burst the sphere.
(3) due to the thermal expansion and contraction of the gas, when the temperature falls in winter or winter, the aluminum balloon should be properly inflated; In summer or when the temperature rises, the aluminum balloon should be properly deflated to avoid bursting. Generally, helium or hydrogen can float for 6-14 hours after being filled, so helium or hydrogen must be filled on the day of use (pay attention to safety when filling hydrogen).
(4) aluminum balloon is not flexible, so please do not fill the ball too full, because the gas is hot and cold, in summer or when the temperature rises, you should deflate the aluminum foil balloon, in order to avoid bursting; In winter or when the temperature drops, the aluminum balloon should be properly replenished. Do not use electric air pump to inflate, you can use hand pump to charge.
(5) If it is accidentally broken during use, you can immediately use transparent tape paste and supplement the gas, and you can use it with confidence.
