One day, I aw the book on uch a funny thing: If under certain condition, platic bottle will be their "water", blowing bubble. I think thi i very intereting experiment, they intend to do their own time, to figure out why the bottle will "drink" bubble blowing.
In accordance with the book on the tip of my better prepare the following material: a few of the flexible traw, a platter, a gla of tap water, a cup of hot water, a cup of ice water, adheive tape, rubber cement, ink, a large platic bottle. After everything i ready, I tart to do the experiment.
The firt tep, I ued rubber cement to eal the bottle, and then ed into a traw.
The econd tep, I put adheive tape with another traw traw with the firt linking the root, o that it can tap into the cup.
The third tep i to look for the experimental ituation will be, I put the ink back into the water dyed blue.
The fourth tep, I put the bottle into a large plate and then bending traw, cup water.
Only four more than the pre-preparation tep, the next tep in the experimental ituation to appear. Firt, I carefully poured with hot water bottle in the platic wall, did not tart one movement, o I continue to上浇water bottle while watching the gla movement, and pretty oon, actually begin from the traw in the bubble! Next on the bottle, "drink" the. I have been part of the refrigerator ice out of the ice water, poured瓶壁to go, eem to tart one failed. I continue to be patient to repeat the action jut a he eye a traw. Hard work pay off, ah, drop from a traw in a true blue ink, the bottle, "drink" again! My experiment a ucce![由Www.haozuowen.com整理]
Included in thi experiment i a cientific reaon热胀冷缩ha the characteritic of object. When the hot irrigated to the outide wall of platic bottle, the bottle thermal expanion of the air, went to the gla, which increae tre, put a cup of water preure to get out bubble on a traw; and when the ice water outide the wall of water into the bottle, the bottle the air wa cooling, the preure inide the mall, water will run into the bottle.
I alo know a lot about life热胀冷缩the ituation, really funny, love the tudent ue their brain, let u explore together!
