This section of Science Experiments web site with egg Science Experiments is about egg floating experiment. Egg floating experiment is one of many egg experiments that are easy to do and you can do it at home.

Equipment needed for the Egg floating experiment

Egg floating experiment is very simple and requires only two glasses, salt, two eggs and of course water.

Method for Egg Floating Experiment

1. Mix plenty of salt (about 10 heaped teaspoons) into half a glass of water.
2. Fill half of the second glass with fresh water (no salt added to this glass).
3. Try floating an egg in each glass.

Result of the Floating Egg Science Experiment

You will find that egg will float in the salt water but not in fresh water. This is because egg is less dense than salt water but more dense than fresh water. Since salt water is more dense than fresh water, it is also easier to float in the sea.

Question: Egg Drop Science Experiment?

I need to drop an egg from six meters for a science class project. But unlike most experiments I need to make something to catch the egg as it hits the ground. No flight alterations can be made. The materials I can use are….
8 straws
1 square foot of cardboard
4 medium or small cups
8 medium or small rubberbands
1 meter of masking tape or half meter of duct tape
12 sheets of copy paper
I can do anything with these materials but they are the only things I can use. Any ideas would be great, all mine have sucked or failed so far.

Answer: Arrange the cardboard so that it is shaped like a deep funnel that will direct the egg in a precise direction on landing (the funnel has to have very angled slides so as to not decelerate the egg just yet, as it could dammage it). Right under the funnel exit, arrange a layer of the 12 sheets of copy paper, held out horizontally one above the other at about 2 cm from one another, loosely held up by their edges to a frame made with the straws and other supplies. As the egg will impact the first sheet, it will drag it down, losing a bit of velocity, hitting the second sheet, draggin theis one, and so on. You may have to experiment a little to see if 2 cm gap is the optimal distance that stops the egg without braking it.

Alternatively, you can cut a complex lacy pattern in the copy paper, to turn them in some sort of tear-away stretchy deceleration catch system.
