今天骄阳似火,但我和爸爸还是兴致勃勃地去钱学森图书馆,参加那里举办的手工制作活动。我们来到二楼的资料厅,参加“水下爆炸”活动。我找了个最佳观察角度的位子坐了下来,仔细地看着老师。只见老师先把一种看起来像糖的粉末放入密封袋中,然后把另一种像面粉的粉末也放了进去。他又用注射器往里面注了点水,最后迅速封上袋子。不一会儿,只见那个袋子越来越大,接着只听见“嘭”的一声袋子就炸开花了。
The sun is burning like a fire today, but my father and I went to the Qian Xuesen Library with interest and participated in the handcrafted activities held there. We came to the information hall on the second floor, to participate in “underwater explosion ” activities. I found the seat for the best angle of observation and sat down, looking carefully at the teacher. I saw the teacher first put a seemingly sugar-like powder in a sealed bag, and then put another powder like flour also put in. He poured another syringe with a little water and sealed it quickly. In a moment, I saw that the bag was getting bigger and bigger, and then I heard a sack of “嘭 ” sacked.
