采用此种方法可吹出五彩缤纷宛如排球大小的氢气泡,也可以吹出连续不断形如网球似的小小彩色气泡.它使氢气密度的演示实验更加新奇生动、更加富有说服力和吸引力.方法如下. 一、吹泡装置的制作 1.找一支废旧的蘸水钢笔,取用其空心笔杆部分,并如图(1)所示截去尾部以达扩孔. 2.找一块厚约5mm,边长20mm见方的有 Using this method, you can blow out colorful hydrogen bubbles that are the size of volleyballs, and you can also blow out small colored bubbles that are continuously shaped like tennis balls. It makes hydrogen density demonstration experiments more novel, vivid, more persuasive, and attractive. Here’s how: 1. Preparation of Blowing Device 1. Find a used fountain pen with a hollow pen holder, and cut off the tail to reach the hole as shown in (1). 2. Find a piece about 5mm thick. Side length 20mm square
