Kitchen Science Experiments

Make a rainbow-colored liquid density column. This project is very pretty, plus it's safe enough to drink.

Experiment Materials: sugar, water, food coloring, a glass

This is the classic science fair demonstration in which you simulate a volcanic eruption using kitchen chemicals.

Experiment Materials: baking soda, vinegar, water, detergent, food coloring and either a bottle or else you can build a dough volcano

Write a secret message, which becomes invisible when the paper is dry. Reveal the secret!

Experiment Materials: paper and just about any chemical in your house

Grow edible crystals. You can make them any color you want.

Experiment Materials: sugar, water, food coloring, a glass, a string or stick

Turn a raw egg in its shell into a soft and rubbery egg. If you're daring you even bounce these eggs as balls. The same principle can be used to make rubber chicken bones.

Experiment Materials: egg or chicken bones, vinegar

Nothing happens if you add food coloring to milk, but it only takes one simple ingredient to turn the milk into a swirling color wheel.

Experiment Materials: milk, dishwashing liquid, food coloring

Make your own pH indicator solution from red cabbage or another pH-sensitive food then use the indicator solution to experiment with the acidity of common household chemicals.

Experiment Materials: red cabbage

Pepper floats on water. If you dip your finger into a water and pepper, nothing much happens. You can dip your finger into a common kitchen chemical first and get a dramatic result.

Experiment Materials: pepper, water, dishwashing liquid

You can make 'hot ice' or sodium acetate at home using baking soda and vinegar and then cause it to instantly crystallize from a liquid in 'ice'. The reaction generates heat, so the ice is hot. It happens so quickly, you can form crystal towers as you pour the liquid into a dish.

Experiment Materials: vinegar, baking soda

Honeycomb candy is an easy-to-make candy that has an interesting texture caused by carbon dioxide bubbles that you cause to form and get trapped within the candy.

Experiment Materials: sugar, baking soda, honey, water
