Science Experiment: Egg In A Bottle
 |
Here is a fun experiment to try with kids or to do at a Science Party. This experiment is easy to do and combines science with a little bit of magic. The key is finding the right bottle for this. You need a bottle that is just a tad smaller than your egg. Some bottles that might work are glass vases, empty milk bottles or glass beakers. |
Science Experiment: Egg In A Bottle
- Safety goggles, please wear at all times.
- Small vase or glass bottle with opening smaller than egg
- Piece of paper
- Matches or lighter
- 1 hard-boiled egg
Science Experiment: Egg In A Bottle
Step 1. Get a small bottle or vase where the opening is just a tad smaller than the egg. Place the egg on top to make sure it does not slide through.
Step 2. Get a piece of paper and fold in half, length-wise. Light a match or lighter and burn the piece of paper. Let the paper burn a bit and then drop it into the bottle.
Step 3. Once the paper is inside the vase or bottle and has some time to burn, place the egg on top of the bottle or vase.
Step 4. You will now see that the egg will slowly slide through the opening into the vase! Voila! Kids love to see this happen and perhaps it’s just this little bit of magic you need to spark an interest in science for kids. To make it even more spectacular, when you place the egg over the vase, cover it up with a red velvet cloth, and mumble some magic words, tap your magic wand…… and you know the rest!
What just happened?
The burning paper heats up the air inside the bottle and causes some of the air to move out of the bottle. When the paper stops burning, the cool air tries to rush back in but the egg is in the way. So the air pressure pushes the air in and with it also the egg.
Now how to get the egg out?
Try blowing inside the bottle to heat up the bottle again. Then tip it over and see if the egg will fall out.
Take this further:
- Try various ways of heating the bottle, for example by filling the bottle with hot water. Does it work?
- Try experimenting with different sizes of bottles. What is the smallest opening that the egg will go through? Measure the diameter and compare.
- Does this experiment work when the room temperature is cold or hot? Try doing this outside when it’s cold out to see what happens.
- Does this experiment work when the air is humid?
