foil balloon, happy birthday, dandelion

Warnings:

Attention! Metallized foil balloons are electrically conductive, so please do not use them near overhead power lines or during thunderstorms, and never let them fly. Never remove balloons that have become entangled in overhead power lines yourself. Do not use metallic ribbon. Attach a balloon weight to prevent accidental flying away. With a string longer than 22cm, the balloon is not suitable for children under 3 years due to the risk of strangulation. Do not inhale or intentionally breathe in the gas from helium-filled balloons due to the risk of suffocation. Please only dispose of helium-filled balloons completely deflated. The balloon can be filled with helium or air (using a straw) via the self-closing automatic valve on the balloon neck and is refillable. In cold air, the balloon loses volume and becomes plump again when warm. Do not expose to great heat or sunlight due to the risk of bursting. For planned summer outdoor use, do not fill it completely full beforehand.
