Looking for a fun science video to share with your child? Bank check out this amazing airship in a bottle experiment!
Today we're welcoming Short Nelson from Make a Kidnection, where he uses stories to make science fun!
The experiment
The egg-in-bottle experiment is one of the classic hands on scientific discipline activities. In the traditional version, yous place a difficult-boiled egg on top of a glass bottle. The egg is plainly wider than the opening, but somehow air pressure sucks information technology right through. Information technology's awesome!
Our "Twist"
Even though I dearest the traditional version of this action, I think information technology can be improved by making one little change. Equally you tin can see in the picture below, I substitute water-filled balloons for the hard-boiled eggs, making information technology the airship-in-bottle experiment.
Advantages of Using Balloons
1) You lot don't have to bargain with hard-humid eggs, and you don't waste eggs.
2) You lot can make the balloons different sizes just by varying how much you lot fill each one, which adds an actress dimension to the experiment. Brand a hypothesis — of those five balloons, which is the biggest one that will fit through the opening? You tin can detect out past watching the video beneath. And even better, do the bodily easily-on scientific discipline activity with your kids later on watching the video.
3) The third advantage is y'all tin depict faces on the balloons and give them some "character." I pretend the balloons are penguins trying to squeeze into their water ice cave earlier the Polar Carry can get them. I'm pretty sure Eeny, Meeny, Minie, and Moe, will squeeze through. Only what near the last 1 — Plumpy?? Will he arrive?
What You lot'll Need
one) Glass bottles similar the Starbucks bottles in the pic above, or plastic bottles, similar the kind apple juice comes in. Whatever bottle volition work as long as it has an opening slightly smaller than the width of the water balloon you're using.
2) ix″ Balloons and permanent markers.
3) Paper and matches to create the vacuum inside the bottle.
See the video below for a step-by-step sit-in of exactly how to do the experiment.
The Super-Fun Introductory Video
We dear doing this science activity using the Plumpy Penguin story and so much that Bob the Dragon and I shot a brusque video to prepare the phase. Watch the middle portion of this video with your kids:
The "Bonus" Video
To reward your kids for doing such a swell chore on this activity, show them this bonus video starring Eeny, Meeny, Minie, Moe, and Plumpy Penguin. It reinforces the idea that easily-on science is fun!
The Science Behind This Activeness
The burning piece of paper heats the air in the bottle, causing it to expand and some of the air to escape out past the airship. (Y'all might observe the balloon jiggling upward and downward while the air rushes out past it.)
When the flame uses upwardly all the oxygen inside the bottle, the paper stops burning. The air in the canteen begins to cool downward and contract, forming a partial vacuum within the bottle.
The air pressure outside the bottle pushing downwardly on the airship is greater than the air pressure level inside the bottle pushing upwards on the airship. That's what causes the balloon to go sucked down into the canteen.
