DIY Science Experiments With Pantry Items

Science in Your Kitchen

You do not need a lab coat or expensive equipment to teach real science. These experiments use everyday ingredients to demonstrate chemical reactions, density, and states of matter.

10 Experiments to Try

1. Volcano Eruption

Baking soda + vinegar = carbon dioxide gas. Add dish soap for foam and food coloring for drama.

2. Rainbow Density Tower

Layer honey, corn syrup, dish soap, water, and oil in a tall glass. Each liquid's different density creates a colorful stack.

3. Invisible Ink

Write with lemon juice on white paper. Heat gently with a hair dryer to reveal the message.

4. Oobleck

Mix cornstarch and water for a substance that is solid when squeezed and liquid when released.

5. Crystal Growing

Dissolve salt or sugar in hot water until saturated. Suspend a string and watch crystals form over days.

6. Milk Art

Add food coloring drops to milk, then touch with a soap-coated cotton swab. Surface tension disruption creates swirling patterns.

Safety Notes

Always supervise young children
Avoid mixing bleach with any other substance
Wear eye protection for splashing experiments
Discuss the science after each experiment
