What you’ll learn: through this experiment kids will be introduced to the concept of air pressure. More specifically they will learn about what occurs when air pressures drop and the power of having two different air pressures in close proximity to one another.
What you’ll need:
- 1 glass bottle (the opening of the bottle must be slightly smaller than the bottom of an egg)
- 1 hard-boiled egg
- 1 piece of newspaper
- 1 match or lighter
*Note: For safety, the use of a match or lighter may require the help from a parent or guardian.
What to do:
- Peel the shell completely off of the hard-boiled egg
- Fold the piece of newspaper so that it is narrow enough to quickly slip into the neck of the bottle
- Light the piece of newspaper and drop it into the glass bottle
- Place the bottom of the egg (the wider end) on top of the bottle so that it is completely covering the neck
- Watch as the fire goes out inside of the bottle, the egg will slowly slip in
Next steps:
- Discuss the process of what happened during the experiment that allowed for the egg to squeeze itself into the bottle.
