Take the Thanksgiving Table Trick Challenge

While the turkey is cooking and everyone is standing around waiting for the meal to start, take out a few kitchen items and entertain your guests. Make sure you practice the challenge beforehand so you can amaze and baffle your audience. Don’t forget to reveal your tricks and your science knowledge. Make your big finish the Table Trick Challenge.

The Amazing Egg Drop
The Egg Drop is a classic science demonstration that illustrates Newton’s Laws of Motion, namely inertia. The challenge sounds so simple… just get the egg into the glass of water, but there are a few obstacles. The egg is perched high above the water on a cardboard tube, and a pie plate sits between the tube and the water. Still think it’s easy? Sir Isaac Newton does.

Tablecloth Trick
The classic “whip off” the tablecloth trick is a must for any aspiring science demonstrator who wants to be amazing! This experiment is guaranteed to either bring down the house or to get you into a lot of hot water. The idea is really quite simple – yank the

Why Does the Water Rise?

Can you make the water rise inside the bottle? With a little scientific knowledge about air and air pressure, you can. This demonstration on the news even brought a surprise for me. In all my years of doing this activity, I’ve never had anything like this occur. Watch the video to find out what happened.

This experiment requires a match and flame, so parental supervision is a must. Take a candle and place it in a pie pan filled with water. Light the candle and cover it with a flask or bottle. The candle needs oxygen to burn. When you cover the burning candle, the flame eventually goes out as soon as all of the oxygen is used up. Since there is no more oxygen under the jar, the rest of the gases (nitrogen, argon, carbon dioxide, and others) exert less pressure than the atmospheric air. The greater atmospheric
