Journal ArticleDigital resources are stored online in your NSTA Library.

The Egg-in-the-bottle was the first demonstration performed by Don Herbert on his “Watch Mr. Wizard” television show, which premiered in 1951. This classic demonstration continues to delight students today and should be included in every middle school teacher’s toolkit. This month’s column offers a new twist on this classic demonstration.

This classic experiment of a hard-boiled egg getting sucked into a bottle is an engaging demonstration of air pressure. The article explains the science behind the demonstration and possible extensions to the activity. Also, once you get the egg in the bottle, you need to get it out. Engage your students on applying what they learned to make it happen.

The author of this article provides easy-to-follow instructions to duplicate this demonstration using an inquiry model of Ask, Do, Explain. For teachers who think that the egg gets ‘sucked’ into the bottle during this demo, the correct explanation is provided. Often teachers show the egg getting pushed into the bottle; this article explains how to get the egg back out, too. This is one of several teaching strategies written in the middle school Science Scope journal in a column called Teacher’s Toolkit.

This demonstration is not new but it is explained here in detail. I liked the ability to use an egg sized water balloon instead of the egg. I hadn’t thought of that before. Safety is reinforced and the extensions provide some good ideas on a tried and true old demonstration.
