为什么热衷于手工，实验？因为太好玩了哈哈哈哈哈。
简单记录陪伴小时光。
材料 Things we need：food coloring色素，baking soda小苏打，vinegar醋，6 test tubs试管，a funnel漏斗 , a tray托盘.
Let's do
步骤 Steps:
1,Put the funnel in the test tube.将漏斗放在试管上
2,Pour some baking soda in the funnel.在漏斗中加入小苏打
3,Put few drops food coloring in the text tube. 试管中加入许滴色素(6个试管中加入不同颜色)
4,Pour the vinegar into all the test tubes ,start from one side and go all the way to the other side.快速在试管中加入醋
Let's learn
原理Principle
Why there are so many beautiful bubbles？
That's very simple.When the baking soda and vinegar mixed together they create a chemical reaction and that causes the bubbles to come out .We add color so that our bubbles look more colorful and beautiful .
小苏打和醋会产生化学反应，生成二氧化碳气泡。加入色素后，气泡更加多彩美丽，6个试管一齐喷发更为壮观。
同样的原理还可以玩跳舞的大米，吹气球的瓶子等...
