Hot air balloon festival

Balloon的红橙黄，让人想起了电阻值的色码（棕红橙黄绿蓝紫灰百黑，1234567890）：

7夕，想去找my girl friend 嫦娥了：

众翁追星，彩球追月：

Say Hi to everyone on the ground, perhaps to my by friend too:

 

远看寰形山有色，近听balloon火无声：

喂！别挤都我，相煎何太急, 世界那么大，你总会找到一个妖娆的girl friend的！

攀天千条路，同仰一月高:

Talk between the balloon and the moon:

Here in the festival, I learnt how to make the hot air balloon fly：

0. Open the balloon package:

1. Spread the balloon on the ground:

 

2. Blow ambient air into the balloon:

3. Blow hot air into the balloon:

4. When enough hot air in the balloon,  air density in the balloon will be lower than air density around the balloon, the balloon will stand up:

5. With more hot air into the balloon, the balloon will fly:

• 老XIA太谦虚了。我估计老XIA甭管到哪，应征的女朋友要排队，要发号，要有专人维持秩序 -永远老李- ♂ (0 bytes) () 08/30/2023 postreply 08:23:34

• 不能攀岩，没有1.8米高，没有80公斤，瘦得护士说有生以来见过的第一瘦。人人见了人人怕，连18岁的见我都跑不暇。 -xia23- ♂ (0 bytes) () 08/30/2023 postreply 08:34:25
