清脆爽口的黄瓜是饭桌上的“常客”。我们可以用黄瓜来做一个小实验,让它“吐水”。实验步骤1在一次性杯子中加入半杯清水,再加入3~4茶匙食盐,用吸管搅拌至食盐完全溶解。2用小刀将黄瓜由中部切开分成两段,再将黄瓜中间部分掏空,形成一个圆柱状的深坑,“黄瓜容器”就制成了。注意黄瓜的底部不能被挖穿。 Crisp and refreshing cucumbers are on the table “regulars ”. We can do a little experiment with cucumbers and let it “spit water”. Experimental procedure 1 in a disposable cup by adding half a cup of water, then add 3 to 4 teaspoons of salt, straw with salt until completely dissolved. 2 Use a knife to cut the cucumber into two segments from the middle and then hollow out the middle part of the cucumber to form a cylindrical pit. The cucumber container is made. Note that the bottom of the cucumber can not be pierced.
