Egg in a Bottle Science Experiment

Achieve the impossible and fit an egg through a bottle using the science of air density and heat.

Egg in a Bottle Science Experiment

The egg in a bottle experiment is a scientific classic that will fascinate kids and teach them about heat and air density. When molecules heat up – in the presence of a flame, for example – they tend to move away from each other. When they cool back down, they move closer, causing what scientists call a “partial vacuum.” This experiment uses the partial vacuum effect to pull an egg through the opening of the bottle, even though it seems too big to fit. Try it out for yourself!

Hard-boiled egg, shelled
Glass bottle with a large opening (such as a large beaker)
A lighter or box of matches
Small strips of paper (about half the size of a standard post-it)
Scissors (for cutting paper)
Small birthday candles

Stand the bottle or beaker right side up on a hard surface.

Using the matches or lighter, light the end of a small strip of paper and quickly toss it in the bottle.

While the paper is still burning, place the egg at the opening of the bottle. Watch as the egg gets sucked into the bottle.

Now try the experiment using birthday candles. Take three candles and stick the non-wick ends into the egg in a cluster formation.

Have a partner hold the beaker or bottle upside down. Light all three candles, and, while holding the bottom of the egg, insert the flamed ends into the opening of the bottle. Watch as the egg gets sucked up into the bottle.

4 Steps to Shedding Your Pandemic Pounds

Forgive yourself, and start walking toward a healthier you.

For those of you who have put on the Pandemic Pounds or added several new COVID Curves, you are not alone. Alarmingly, the American Psychological Association has recently published that almost half of all adults in their survey now have a larger physique. In fact, 42% of people reported gaining roughly 15 pounds (the average published was surprisingly 29 pounds but that included outliers) over the past year. Interestingly, 20% of adults in this survey lost about 12 pounds (I am surely not in this group). Clearly, there is a relationship between stress and weight change. In addition, one in four adults disclosed an increase in alcohol consumption, and 67% of participants distressingly revealed that they have new sleeping patterns.

This past year has brought about what has been called the 'new normal.' Social isolation and inactivity due to quarantining and remote working have sadly contributed to the decline in many people's mental and physical health, as demonstrated by the widespread changes in people's weight, alcohol consumption, and sleeping patterns. Gym closures, frequent ordering of unhealthy takeout, and increased time at home cooking and devouring comfort foods have had a perceptible impact. In addition, many people have delayed routine medical care and screening tests over fear of contracting Covid-19 during these visits. Unfortunately, the 'new normal' has now placed too many people at risk for serious health consequences, including heart attacks and strokes.
