SAFE Balloon / Leisure activities

SAFE Balloon

People always feel scared when blowing balloon, because they don’t know when the balloon will reach a saturated state. In case of blowing for a short time, the balloon won’t be full enough, in case of blowing for a long time, the balloon will blast, and people are afraid of this, at the same time, it may bring harm to them.
Density formula: P = M/V We use the density change theory according to the variation characteristic of the balloon. The color of the tip text on the balloon will become lighter along with the increase of the balloon surface, and will disappear finally.
