(1) due to the aluminum film balloon without shrinkage and to the aluminum film balloon inflation must be slow, be cylinder filled to 90%, in order to avoid bursting at the seams. If you have 2 layers of aluminum film sticky situation, be sure to stop charging, gently with the hand will be 2 layer of aluminum film pulled open again, otherwise easy to damage.

(2) sharp objects, not clean the ground, the sun direct and excessive extrusion are easy to damage the sphere, burst

(3) due to thermal expansion and contraction of the gas, lower winter temperatures or should be appropriate to the aluminum film balloon; summer or increase in air temperature, should be appropriate to the aluminum film balloon deflated, so as not to break. Generally filled with helium or hydrogen gas can float for 6-14 hours, so helium or hydrogen must be used in the day of the use of (charge of hydrogen must pay attention to safety Oh!)

Aluminum foil balloon does not recommend the use of a large pressure of electric pneumatic pump, easy to break through the balloon!
